Russian Prime Minister Mikhail Mishustin has arrived in China, Moscow's foreign ministry said, for a visit in which he will meet with President Xi Jinping and ink a series of deals on infrastructure and trade.

Mishustin arrived late Monday in Shanghai, the ministry said, where he was greeted at the airport by Moscow's ambassador to China Igor Morgulov and Beijing's top diplomat to Russia Zhang Hanhui.

He will take part in a Russian-Chinese Business Forum and visit a petrochemical research institute in Shanghai, the Kremlin said, as well as hold talks with "representatives of Russian business circles".

China last year became the top energy customer for Russia, whose gas exports had otherwise plummeted after a flurry of Western sanctions over its military campaign in Ukraine.

Mishustin will then travel to Beijing, where he will meet with Xi and Premier Li Qiang, Russian state media TASS has said. (AFP)
