The groundless accusations recently made by the U.S. media about artificial origin of novel coronavirus are unproven and unacceptable, Kremlin spokesperson Dmitry Peskov said at a media briefing on Wednesday.

Since the COVID-19 outbreak, experts from Russia and China have maintained communication and exchange of information. At present, Chinese experts are actively developing a coronavirus vaccine, and the Russian side is also promoting this process in many ways, Peskov said.

He emphasized that it is imperative for China and Russia to carry out international anti-epidemic cooperation. Meanwhile, Russia will continue to maintain dialogue and cooperation with China, he added.
