The behavior of Chinese citizens in Russia who went back to China through illegal ways – causing imported cases of COVID-19 – was immoral, said Chinese Ambassador to Russia Zhang Hanhui during an interview on Friday.
He added that allegations claiming it was Russia that required them to go back to China is an act of escaping responsibility, and will harm bilateral relations.
According to virological analysis and tracking, it is true that some people were infected in Moscow, but a considerable number of cases were infected during the return trip, the ambassador noted.
The imported cases have added pressure to prevention and control work in China, he said.
"I want to stress two aspects. First, the passenger inspection of the land port between China and Russia will never be opened again until the final win against the virus, and second, Chinese citizens in Russia should arrange well their quarantine life there," Zhang said.
Talking about situation in Russia, Zhang pointed out that it is getting tense as large numbers of Russian tourists and expatriates visiting Europe where has severe infection have been back to Russia, which greatly increases the risk here.
