The second batch of 10 Russian Sukhoi Su-35 multipurpose fighter jets will be delivered to China this year with a further 10 aircraft in 2018, TASS reported on Thursday, citing its sources.
"The first four planes were supplied late last year and the second batch of 10 jets will be delivered to the customer this year," said an unnamed source familiar with the matter.
In November, Deputy Director of the Federal Service for Military and Technical Cooperation Vladimir Drozhzhov told TASS that Moscow had started deliveries of the fighter jets to China.

The contract for 24 Su-35s was inked in November 2015, making China the first international buyer of the advanced Russian warplane. The three-year deal for the aircraft, ground equipment, and spare engines is valued at $2 billion.
The Su-35 is a long-range '4++ generation' super-maneuverable fighter jet. It is armed with an internal 30mm cannon and has 12 hardpoints with a combined capacity of 8,000 kg, compatible with a wide range of unguided and guided missiles and bombs. Its maximum speed is 2,500 km/h, with a range of 3,400 km, and a combat radius of around 1,600 km.
Beijing first showed an interest in buying Su-35s in 2008 during the Airshow China international expo. Formal negotiations started in 2011.
China is currently among the world’s top five buyers of Russian arms, restoring its position after a slowdown in the late 2000s.
