Prime Minister David Cameron said on Thursday it was time to join air strikes against Islamic State in Syria because Britain cannot "subcontract its security to other countries".
Since last month, U.S. warplanes have struck Islamic State's oil infrastructure in Syria in a stepped-up campaign of economic warfare that the United States estimates has cut the group's black-market earnings from oil by about a third.
China needs to deepen its fight against separatists, intensify "de-radicalization" efforts, and increase global cooperation to defend against terrorism, the country's domestic security chief wrote on Tuesday.
