Before President Xi Jinping's visit to Russia and Africa, China and Russia signed two major contracts on the sale of arms.
According to the contract, the two countries will jointly produce four Lada Class air-independent propulsion submarines which will then be sold to China. China will also buy 24 Su-35 jet fighters from Russia. Experts say that the Su-35 will reduce the pressure on China's air-defense before China's stealth fighter is put into use.
This is the first time China has bought important military equipment from Russia in ten years. The Defense Ministries of both countries have said that military cooperation between the two countries is of great significance in maintaining regional stability.
