Li Wei, an anti-terrorism expert at the same institution, said building an international alliance against terror is no longer an issue, adding, "The biggest problem is insufficient cooperation in a global context."

Teng Jianqun, a senior US studies research fellow at the China Institute of International Studies, said the Paris attacks took place ahead of global events including the G20 summit and the global climate change conference

In his speech on Sunday, Xi also addressed economic issues. He called for increased coordination on macroeconomic policies among various parties and for a stronger say and representation for developing countries and emerging-market nations on the global governance system.

As emerging-market nations have contributed to more than 50 percent of world economic growth, they are still an important engine for global economic expansion, Xi said.

Huang Wei, an economic governance researcher at the Chinese Academy of Social Sciences, said the BRICS nations "have huge room for improvement" when it comes to cooperation.
