The measures announced by the vast, landlocked country are the most drastic steps taken by any nation so far over concerns about a coronavirus which has rapidly spread across China.

Mongolia has not recorded any cases of the pneumonia-like virus, which has killed at least 81 people in neighbouring China and more than 2,700.

Almost a dozen countries have found cases, including in Europe, Asia and the United States.

Vice Prime Minister Enkhtuvshin Ulziisaikhan said the decision was made because cases have been confirmed in China’s neighbouring region of Inner Mongolia.

“Pedestrians and cars are prohibited to cross the Chinese border,” Enkhtuvshin said on Sunday, saying the schools and universities would stay shut until Mar 2, along with other public places such as gaming centres.

“Public events are also prohibited. Public events mean conferences, any public gatherings such as sports, entertainment or travel, and competitions,” he said.
