As one of the largest countries in the world, China and Russia have signed a number of cooperation agreements in the past few years, covering energy, transportation, agriculture, finance and other fields. Among them, cooperation on large-scale projects such as the China-Russia East Route Natural Gas Pipeline with a total length of about 3,000 kilometers and the China-Russia Siberia Crude Oil Pipeline have further strengthened the cooperative relationship between the two countries.

On May 4, Russian President Vladimir Putin once again sent a major gift to China. From June 1, 2023, Russia will open Vladivostok to China and set up a free trade zone to allow China to conduct trade activities in the port.

In fact, this news cheered the Chinese government and people, because China has been waiting for this decision for 163 years. So, do you know why Russia suddenly opened Vladivostok to China? How important is this port to China?
