Twenty-one agreements were signed between China and Russia on Monday to further promote cooperation in various fields, including on high-speed railways, during Premier Li Keqiang's visit to St. Petersburg.

Li and his Russian counterpart, Prime Minister Dmitry Medvedev, witnessed the signing of the agreements - which also included civil nuclear power technologies, energy projects and linking China's Belt and Road Initiative with the Russia-dominated Eurasian Economic Union-after the 21st China-Russia Prime Ministers' Regular Meeting in St. Petersburg.

Premier Li arrived in St. Petersburg on Sunday, the fourth stop of an eight-day Eurasian trip that has also taken him to Kyrgyzstan, Kazakhstan and Latvia. He was accompanied by Medvedev to visit the State Hermitage Museum, a UNESCO World Heritage Site.
