Beijing's No 3 Li heading for Moscow

China's top legislator Li Zhanshu will visit Russia this week, according to state media, becoming the highest-ranking Communist Party politician to travel to the country since Moscow's invasion of Ukraine.

Li, 72, who is chairman of the National People's Congress Standing Committee and ranks third in the mainland government hierarchy, will pay official visits to Russia, Mongolia, Nepal and South Korea from Wednesday until September 17, according to Xinhua News Agency.

He will attend the Eastern Economic Forum due to be held over four days from Monday in Russia's far eastern city of Vladivostok.

Beijing and Moscow have drawn closer in recent years, ramping up cooperation as part of what they call a "no limit" relationship, acting as a counterweight to the global dominance of the United States.

Meanwhile, tensions between China and the West have risen as Beijing has refused to condemn Moscow's invasion of Ukraine and provided diplomatic cover by blasting Western sanctions and arms sales to Kyiv.

Li is likely to retire from his role in the Communist Party at a landmark conference next month, where President Xi Jinping is expected to secure a precedent-busting third consecutive term in office.

Xi himself has not left China since the start of the pandemic in early 2020.

Xi and Russian leader Vladimir Putin announced their "no limit" strategic partnership in February, weeks before Russia invaded Ukraine in what Putin calls "a special military operation."
