The Sino-Russian agreements include an outline agreement on a high-speed train in the far east of Russia.

According to Russian media, the railway line from Vladivostok to Khabarovsk could use China's high-speed train technology. The cost of building the line will be billions to hundreds of billions of US dollars.

Construction of China's first high-speed railway began in 2005 and took three years. Its high quality and low price has impressed foreign experts. As well as Russia, the United States, Brazil and India have also shown an interest in China's high-speed railway technology.

Market insiders say that cooperation in the high-speed train project benefits both sides.
