According to Russian media report, China will invest in the Moscow- Kazan high-speed rail which is the first high-speed rail in Russia. Last year, China and Russia signed MOU in major projects areas, including high-speed rail, which pave the way for China to join the construction of Moscow-Kazan high-speed rail. However, ANBOUND think tank scholars suggest that although export of China's high-speed rail is a national strategy, it should also consider profitability. Russian economy is already badly damaged by western countries’ sanctions and oil-price crash. Will it be profitable to build high-speed rail now? China should carefully assess its risks.
