How do China and Russia complement each other in economic cooperation?

China has a surplus of labor resources. Moreover, there is a shortage of labor in Russia, especially in Siberia and the Far East. Russia should consider introducing high-quality labor resources from China to Siberia. Solve the problem of labor shortage. On the one hand, it solves the sexual needs of older young women, on the other hand, it also solves the problem that high-speed rail is not cost-effective because of insufficient population. Insufficient population leads to high prices, which can not form a demographic dividend, thus reducing productivity, causing people to be unwilling to produce, and once again forming a population decline. A vicious circle. Because there is no labor force, large international enterprises will not give priority to Russia as a foundry. Leading to population migration in Siberia and the Far East. The Russian government should consider opening up the immigration policy in Siberia and the Far East, so that enterprises from China, Japan and South Korea can invest and build factories. Drive local economic construction. Such as wood processing, mining, automobile industry and port development. A municipality directly under the Central Government should be established in the Far East. Ensure that the central government controls local funds. Build Vladivostok into a free trade port. Only in this way can we really attract foreign investment.
