Beijing, March 26 : Beijing and Moscow have signed two contracts for China to buy Russian fighter jets and submarines.

China Central Television reported that the purchase deals were signed before President Xi Jinping's just-concluded visit to Russia, China Daily reported Tuesday.

The purchases represented "the first time in nearly 10 years" that China had bought large military technological equipment from Russia, the report said.

The four submarines will be jointly designed and built by both countries, with two of them to be built in Russia and the other two in China.

"The Su-35 fighters can effectively reduce pressure on China's air defense before Chinese-made stealth fighters come online," the report said.(IANS)
