Russia begins delivering S-400 air defence systems to China

Russia has begun delivering the Almaz-Antei S-400 Triumf self-propelled surface-to-air missile (SAM) system to China under the terms of a contract signed in 2014, TASS news agency cited an unnamed source close to the Russian military-industrial complex as saying on 18 January.
The source, who did not reveal how many S-400s are set to be delivered, pointed out that the contract did not envisage either a technology transfer or licensed production of the systems.
