China, Russia sign missile-defense deal

China and Russia have signed an agreement on the sale of Russia's S-400 surface-to-air missile system, a senior manager of Russia's leading technology corporation said on Wednesday.

In addition, Russia is planning to use China's spacecraft equipment, Dmitriy Shugaev, deputy CEO in charge of international affairs at Rostec, a State-owned company in charge of Russia's arms exports, told China Daily.

He said that the S-400 deal "is important to both Russia and China" and China will be the first foreign user of the missile system, but he declined to reveal the deal's details, saying they "are too sensitive to be revealed".
