Fang Fenghui, chief of the General Staff of the PLA, has said that China-Russia drills will improve the two forces' coordination capabilities and help them maintain regional security and stability.

The simulated enemies of the joint forces in the Joint Sea 2013 and Peace Mission 2013 drills are obvious: pirates and terrorists. So people who allege that China and Russia are targeting a third country or that they are trying to establish a "military alliance" are only betraying their Cold War mentality.

On the contrary, it is the United States that is trying to "encircle" China and contain Russia by pushing ahead with its "pivot to Asia" strategic policy. Supporting the US move is Japan, which is hell-bent on disowning its history and whitewashing its war crimes, and reverting to its past militaristic policies by playing up the "China-Russia military threat" theory. The US and Japan have made little effort to conceal their intentions of containing China and Russia by holding frequent joint large-scale drills and bolstering their military presence in East Asia.

Third, China-Russia joint drills will have a great impact on the future of regional security. There is little doubt that Peace Mission 2013 will act as deterrence against terrorists and help give shape to the region's security map.

The global situation is getting more complex with some Western powers trying to interfere in the internal and bilateral affairs of other countries, and the unrests in the Middle East and North Africa.

Also, the US-led NATO combat troops will complete their withdrawal from Afghanistan at the end of next year, after which the country could again become a hotbed of the "three evil forces" of extremism, terrorism and separatism.

Under such circumstances, SCO member states have to devise a foolproof counter-terrorism strategy through deeper cooperation and better coordination. And as the two major powers in the SCO, China and Russia have to take the lead in working out such a strategy, which is integral to the stability of the region.

Though armed forces act as deterrence against terrorists, they have to be promptly deployed to be of effective use in real combat situations, for which drills are a necessity. And this is the principal reason why China and Russia have been holding joint counter-terrorism drills under the framework of the SCO.
