In another sign that the US is being sidelined in Syria, China is reported to be sending cruisers into the coast of Syria in a move to show support to the Russian anti-ISIS/L initiative.
This is on top of the Iraq decision to share critical  intelligence to the Syrian forces which shocked the White House recently.

“According to the Russian Senator Igor Morozov, Beijing has taken decision to take part in combating IS and sent its vessels to the Syrian coast.
Igor Morozov, member of the Russian Federation Committee on International Affairs claimed about the beginning of the military operation by China against the IS terrorists. “It is known, that China has joined our military operation in Syria, the Chinese cruiser has already entered the Mediterranean, aircraft carrier follows it,” Morozov said.
According to him, Iran may soon join the operation carried out by Russia against the IS terrorists, via Hezbollah. Thus, the Russian coalition in the region gains ground, and most reasonable step of the US would be to join it. Although the stance of Moscow and Washington on the ways of settlement of the Syrian conflict differs, nonetheless, low efficiency of the US coalition acts against terrorists is obvious. Islamists have just strengthened their positions.
As Leonid Krutakov told Pravda.Ru in an interview, the most serious conflict is currently taking place namely between China and the US. Moscow may support any party, the expert believes, and that is what will change the world order for many years.”
