China’s northwestern province of Shaanxi has reported seven new imported cases of the novel coronavirus, all in citizens returning home from Russia, even as domestic cases in the country were largely curbed.

The port city of Manzhouli in Inner Mongolia also reported three new imported cases, without giving details, according to a Reuters report.

China has instituted stringent checks at its ports and border points, banning the entry of foreign nationals on March 28, and even diverting international flights from its capital city Beijing.

Still it has faced a continuous trickle of cases brought in by Chinese citizens wanting to return home in spite of risks of getting infected. In recent days, many of these have come back from Russia.
