Researchers sent by the World Health Organization have arrived to Wuhan, China, the city where the coronavirus pandemic was first traced, to investigate its origins.

The 10-member team approved by President Xi Jinping’s government, includes scientists from the United States, Australia, Germany, Japan, Britain, Russia, the Netherlands, Qatar and Vietnam.

Scientists suspect the virus jumped to humans from bats or other animals. Beijing, stung by accusations it allowed the disease to spread, says the virus came from abroad, but foreign scientists say that is unlikely.

According to the Associated Press, spokespeople for the Chinese government have said that they will “exchange views” with the WHO scientists, but did not indicate if they would allow the scientists to gather evidence.
