China and Russia signed 15 cooperation documents totalling 1.6 billion U.S. dollars?Saturday in Vladivostok, Russia.

Representatives of the governments and business communities of the two countries signed the documents covering economic, technological, energy and infrastructure cooperation.

The agreements were signed after visiting Chinese Vice-President Xi Jinping held a meeting here on strengthening China-Russia interregional cooperation, known as the symposium on China-Russia Ussuriysk economic and trade cooperation area.

At the meeting, Xi heard reports given by top leaders from the Chinese Ministry of Commerce, China's Heilongjiang Province and Wenzhou City and Chinese enterprises.

Xi said Russia's Far East area and China's northern frontier provinces were important trading partners and should enhance bilateral cooperation.
