Previously, on the website of the Civil Aviation Administration of China, it was possible to see and check the availability of all direct flights that operate between China and any other country in the world.
Earlier today, the largest air ticket seller in Russia, Aviasales, announced which international airlines "will definitely fly abroad from Russia" after March 8, 2022 and China is not listed at all in this list of countries and airlines, that is, the largest air ticket seller in Russia Aviasales does not confirm the availability of flights between Russia and China after March 8, 2022 at the moment.
Yesterday we wrote that the Russian company Aeroflot announced that after March 8, 2022, Aeroflot would fly abroad only to Belarus, although in 2020-2022 the Russian company Aeroflot flew to two cities in China from Russia, and the Chinese airline AirChina flew from Beijing. China to Moscow, Russia and back in 2020-2022 earlier.
Therefore, formally, only the flights of the Chinese airline AirChina from Beijing, China to Moscow, Russia and back remained.
At the time of this writing, if you check the website of the Civil Aviation Administration of China for any direct flights from Beijing to Moscow and from Moscow to Beijing, then the search shows no data (see screen below). Although earlier these data were and it is not yet clear what caused this, whether the flights of the Chinese airline AirChina from Beijing to Moscow and back will be canceled.
Maybe these flights are temporarily canceled or there will be a change in the flight schedule, maybe it's just a mistake on this website of the Civil Aviation Administration, but so far we have not been able to find any official comments from the Civil Aviation Administration of China on this matter.
