Russia said on Tuesday it was preparing for the potential spread of China's coronavirus as authorities closed schools and canceled public events in some regions, though officials attributed that simply to flu.

Russia has a 4,300-km (2,670-mile) land border with China and last week reported its first two cases of coronavirus in Siberia. Both involve Chinese nationals.

Moscow has restricted border crossings from China, suspended direct passenger trains and commercial flights, except for some that are being routed through a separate terminal at a Moscow airport to make screening passengers easier.
