The African community in Guangzhou is on edge after widespread accounts were shared on social media of people being left homeless this week, as China's warnings against imported coronavirus cases stoke anti-foreigner sentiment.

In the southern Chinese city, Africans have been evicted from their homes by landlords and turned away from hotels, despite many claiming to have no recent travel history or known contact with Covid-19 patients.

CNN interviewed more than two dozen Africans living in Guangzhou many of whom told of the same experiences: being left without a home, being subject to random testing for Covid-19, and being quarantined for 14 days in their homes, despite having no symptoms or contact with known patients.

Health authorities in Guangdong ​province and the Guangzhou Public Security Bureau did not respond to CNN's request for comment.

The move comes amid heightened media coverage of the so-called second wave of coronavirus cases, emanating from infections outside of China.

Earlier this week, Chinese President Xi Jinping urged authorities to carefully watch for imported cases from ​other countries, state news agency Xinhua reported.

But one aspect of the data has received relatively less public attention: on March 26, Vice Minister of Foreign Affairs Luo Zhaohui said 90% of China's imported cases held Chinese passports. 

On Thursday afternoon, Chinese Foreign Ministry spokesman Zhao Lijian said: "Since the beginning of the coronavirus outbreak, China and African countries have always supported each other and have always fought against the virus jointly.

"I would like to emphasize that the Chinese government treats all foreigners in China equally, opposes any differentiated practices targeted at specific groups of people, and has zero tolerance for discriminatory words and actions."

Cases spark a backlash

Guangzhou has long had the largest African community in China. Because many Africans in the city have short-term business visas, they travel into China several times a year, making it difficult to calculate the size of the African population the city.

But in 2017, approximately 320,000Africans entered or left China through Guangzhou, according to Xinhua. African residents say local hostility to their presence is nothing new.

But when coronavirus cases emerged in the African community this month it served to amplify existing tensions. 

A report on April 4 alleged that a Nigerian national with Covid-19 had attacked a Chinese nurse who tried to stop him leaving an isolation ward at a Guangzhou hospital​.

The report was shared widely on social media, and local Africans CNN spoke to say a racist backlash against the African community ​followed. 

Then on April 7, Guangzhou authorities said five Nigerians had tested positive for Covid-19. 

Fearing a cluster among the African community, Guangzhou authorities upgraded the risk level of Yuexiu and Baiyun, the areas home to the city's two African enclaves, from low to medium, state-owned Global Times reported.​

The local government Tuesday reported 111 imported cases of Covid-19 in Guangzhou, with 28 patients from the UK and 18 from the US.

In interviews with CNN, Americans and British nationals in Guangzhou said they had not heard reports of forced testing, home evictions and additional quarantine measures being imposed on members of their communities. 

On Saturday, however, the US Consulate in Guangzhou warned African-Americans to avoid travel to the city.

"In response to an increase in Covid-19 infections, officials in the Guangzhou metropolitan area escalated scrutiny of foreign nationals," the consulate said in a statement.

"As part of this campaign, police ordered bars and restaurants not to serve clients who appear to be of African origin. Moreover, local officials launched a round of mandatory tests for Covid-19, followed by mandatory self-quarantine, for anyone with 'African contacts,' regardless of recent travel history or previous quarantine completion. 

"African-Americans have also reported that some businesses and hotels refuse to do business with them."

Homeless in Guangzhou

On March 21, Nigerian goods trader Chuk, who did not want to use his full name for fear of government reprisals, flew back to Guangzhou, his home since 2009.

With China's coronavirus cases seemingly under control, he wanted to resume his trading business, which had been stymied by the pandemic.

The area around Guangzhou is a manufacturing heartland, where many Africans buy cheap goods to sell back home.Chuk returned seven days before China closed its borders to most foreign nationals, but upon arrival, he says he was told that he needed to enter government quarantine at a hotel for two weeks. 

As a trader, Chuk travels frequently, and is accustomed to staying in hotels during his time in China. 

But on Tuesday, Chuk says that when he was released, along with about 15 other Africans, with a clean bill of health, they effectively became homeless.

"We went to the hotel with the certificate, but we were rejected," he said. The group went to the police station to report that hotels were refusing to let Africans stay, but "they refused to talk to us." 

The Guangzhou Public Security Bureau, which oversees the police, did not respond to CNN's request for comment about events described by anyone CNN interviewed. 

Chuk says he had no choice but to sleep rough for two nights, before finding a friend's couch to crash on. "Rain fell that day and the next and we were all drenched and our belongings soaked," he said.

His story was echoed by others who spoke to CNN.Earlier this week, images began circulating online of rows of Africans sleeping on the streets of Guangzhou, beside their luggage, having either been evicted from their apartments or been turned away from hotels.

Other videos showed police harassing Africans on the street. 

Imported cases discrimination

The five Nigerians confirmed to have Covid-19 had been to eight restaurants, nine hotels and 12 public places before testing positive, according to the state-run Global Times. 

Since then, Africans across Guangdong province have reported being tested in their homes, despite having no recent travel history or contact with a Covid-19 patient.

Maano Gaasite, an international student from Botswana at a Guangzhou university, said that at 3 p.m. on Sunday she received a WeChat message from her course administrator saying she needed to be tested, despite having not left China for over six months. An African restaurant in the San Yuan Li area of Guangzhou, near where five Nigerians tested positive for the virus.

"It was only when I got there I realized it was only African students. There are other students from India (in my halls of residence, but) they were all not there. Just our small community (of Africans)," she said.

The officials took a swab from the back of her throat and said they would call if she had the virus. She never heard back. As a student, Gaasite says she has no contact with the Nigerian trading community. 

Meanwhile, in Shenzhen, a city about 140 kilometers (87 miles) south of Guangzhou, Youssouf, a Senegalese man who did not want to disclose his surname for security reasons, said that at 1 p.m. on Wednesday, the Chinese authorities came to the apartment he shares with his Canadian wife in a compound with many foreign residents. Police come to the house of an African resident in Beijing."They knocked on the door. A guy showed me his phone with my full address, my full name and my country," said Youssouf.

He told Youssouf to go to hospital by 5 p.m. to get tested. Youssouf asked if they also wanted to test his Canadian wife. Neither of the couple had left China in the past 12 months.

"They said, 'No we are just testing Africans,'" Youssouf said. Canada has more than 20,000 confirmed cases of coronavirus and is on the Chinese Ministry of Foreign Affairs' list of high-risk countries. 

The Shenzhen municipal health commission did not respond to CNN's request for comment.

"African people are not welcome in China. We've been discriminated against repeatedly," he said.

Africans in China have long complained of racism, in the form of Chinese people holding their noses as they walk past, racially offensive adverts on television, and Chinese actors performing in blackface in a nationwide gala. 

Earlier this year, when Beijing proposed changes to its immigration laws around permanent residency, a backlash emerged on Chinese social media site Weibo against Africans. Many of the comments have since been removed from the platform. Africans stand in front of the Don Franc hotel in Guangzhou, before the coronavirus crisis.

Africans on lockdown

Smith, the American expat who helped coordinate the food drop, lives in Guangzhou with her Moroccan boyfriend.In late February, the couple went on holiday to Malaysia.

She returned on March 17, and says she was was asked to self-isolate at home for 14 days.

He returned on March 25, and says he went into a government quarantine facility, paying 400 yuan ($56) a night at a designated hotel, and emerged on Wednesday after testing negative twice.

On Thursday, health authorities came to the couple's flat and said that Smith's partner, who did not want to be identified in this piece, would have to quarantine at home for 14 days because all Africans in the city were being put on lockdown, Smith says.

Smith says her employer, an international school in Guangzhou, was informed on Thursday that all Africans needed to go into lockdown, as it has several South African employees.

CNN has spoken to several other Africans who were visited by authorities on Thursday and told they needed to quarantine at home for 14 days.

They say police put alarms on their front doors, which will alert officials if they leave home.

There have been no public statements confirming or refuting the existence of an official policy about these measures.Smith was told if she chose not to live in the apartment she shares with her African boyfriend, who has twice tested negative for the virus, she would not have to quarantine.

"There's resentment in Guangzhou that a lot of Africans are perceived to be here illegally and that they overstay," said Smith.

"There's been a push in Guangzhou to get them out. This has been an easy excuse to push this community out." Police come to the house of an African resident in Beijing.When the authorities came to Peter Busari's Guangzhou apartment on Wednesday to test him, he filmed the exchange and went live on Facebook.

That footage shows officials also asking to see his passport and checking his visa. 

Wang Wei, a PhD candidate at the University of Hong Kong, who has been studying the African community in Guangzhou for several years, said testing Africans gave the government a chance to conduct a mass checking of passports, too.

"It threatens the undocumented Africans," he said.

"Officially, African foreigners (in Guangzhou) decrease every year but we all know that undocumented Africans still live in this circle doing business underground or through brokers. But because of the pandemic they will become exposed."

Those caught overstaying their visas will be taken into police custody, asked to pay a 10,000 yuan ($1,421) fine and often charged for their airfare back to their home country, said Wang.

Roberto Castillo, an assistant professor at Lingnan University, who has researched the African community in Guangzhou for nearly a decade, says the Yuexiu district where the Nigerian Covid-19 cases were found has "historically been a place where the African community is in more tension with the authorities," and was a troubled site during the Ebola crisis of 2014, when Africans of all nationalities were stopped and checked, regardless of whether they were from affected nations.

In 2009, a riot among Africans was sparked in Yuexiu after a Nigerian man who was rumored to be undocumented was injured jumping from a building to avoid a passport check. 

Africans in Guangzhou have been encouraged to leave the city in recent years through a series of immigration policies, economic developments and heightened policing. 

Meanwhile, on Thursday reports emerged from Africans in China that the crackdown on Africans is wider than Guangzhou. One Ghanaian family in Beijing, with no recent travel history or contact with Covid-19, reported that police came to their apartment in the early hours of Thursday morning and ordered them to leave.

The Ghanaian embassy in Beijing confirmed that two Ghanaian nationals were currently seeking refuge there, but declined to comment. Africans in Chengdu and Fujian province also told CNN they had been visited by community officials. 

China-Africa relations

"Why are we being discriminated against like this? Are there no Chinese in Africa?" one African is heard asking a Chinese policemen on the street in Guangzhou, in a video shot on Thursday evening, as many faced another night sleeping rough on the streets of the city.

It is a question that speaks to the implications a crackdown on Africans in China could have on Beijing's bilateral relations with governments on the continent, which they have courted with investments for decades and where anti-Chinese sentiment is already rumbling.

About 1 million Chinese are estimated to be living in Africa. On Twitter, one user noted that Kenya allowed a plane of Chinese nationals to land in Nairobi, at the height of China's crisis, but when the virus reached Africa the same compassion had not been shown in Guangzhou.

On late Thursday night, local time in Abuja, Nigerian Foreign Affairs Minister Geoffrey Onyeama tweeted that he had invited the Chinese Ambassador to Nigeria Zhou Pingjian to communicate his government's "extreme concern at allegations of maltreatment of Nigerians in Guangzhou."

China has been trying to position itself as a friend to African states, as they battle the virus.

Li Mingzhu, an official at the National Health Commission, said earlier this month that China has been sending medical teams to African countries for 57 years and would continue to offer help to African countries to improve their ability in combating the novel coronavirus outbreak.

But not all African nations are satisfied with that.

Ghana's finance minister called on China to ease African countries' debt burden earlier this month, while on March 31, Blessings Ramoba, President of Mining Forum of South Africa, tweeted that the coronavirus had caused the South African economy to lose "billions of rand."

"The Chinese govt (sic) must cancel the debt owed by South Africa as a sign of remorse," he said.Zhao Lijian, the Chinese Foreign Ministry spokesperson, addressed the matter of debt earlier this week, saying: "I believe China will resolve these countries' difficulties via consultation through diplomatic channels." 

Castillo said one reason the Chinese might be cracking down on Africans in Guangzhou is because they don't trust the low numbers being reported by various nations. But to acknowledge that could be diplomatically awkward."It's already a PR mess for China," said Castillo.

"When they're doing this to foreigners, it's just exacerbating the negativity."
