On Sunday, China reclassified Shulan, a city near the Russian and North Korean borders, as high risk. Country's national health commission reported 17 new cases on Sunday. The authorities reported five locally transmitted cases were in three provinces which border Russia or North Korea, including three in Jilin, and one each in Heilongjiang and Liaoning.
