5 October 2015. In a bid to strengthen the Russian air campaign, another Syrian ally -- China -- is now planning to deploy Shenyang J-15, a carrier-based fighter aircraft, in Syria. Several reports have stated that Beijing has agreed to join the Russian air campaign. The development has come mere days after Chinese Foreign Minister Wang Yi told a UN Security Council meeting that the world can no longer afford to stand by and look on with folded arms but must also not "arbitrarily interfere" in the Syrian crisis.
