These days the U.S. is now becoming vocal criticizing China.

The U.S. Department of Defense in its 2013 "report on Chinese military and security posture development" presented to Congress accused the Chinese government and army of cyber hacking against the government institutions and enterprises of the U.S.

In the wake of the publication of the report, U.S. high-ranking officials and media accused China, claiming it lacks transparency in its military modernization as evidenced by Beijing's spending of more funds for defence than what was made public and its consequences are a matter of concern.

The U.S. escalation of its criticism of China since its transfer of strategic pivot to the Asia-Pacific region has sparked off a strong rebuff of the army and government of China.

The Chinese People's Liberation Army flatly brushed aside the U.S. accusation as it failed to produce evidence enough to prove the China's involvement in cyber hacking.

A spokesman for the Chinese Foreign Ministry warned that the U.S. repeated mud-slinging would adversely affect the relations between the two countries.

The U.S. is now plugging its satellite forces in the Asia-Pacific region into its operation to contain China.

UPI reported the U.S. administration allowed Japan to deploy drones on Guam in a bid to turn it into an important strategic outpost in operations against China and agreed with Tokyo to jointly monitor the Asia-Pacific region.

Meanwhile, the Pentagon formally informed Congress that it would sell to south Korea four Global Hawks used in Afghanistan, etc.

China is taking countermeasures against the U.S. moves to knock into shape an alliance against China with its satellite forces.

The Pentagon asserted that China began deploying Dongfeng-21D missile with a range of 1 500 km, grumbling that the deployment of this missile reportedly tasked to mainly strike enemy's aircraft carriers would be a grave threat to the U.S. in its operations in Asia and Western Pacific.

Washington did not hide its concern that China put its first aircraft carrier Liaoning into commission and is mulling building other carriers and increase the number of nuclear-powered submarines to eight to the maximum from the present three in the 15 years to come.

It was against this backdrop that the Navy of the Chinese People's Liberation Army staged drills of its northern sea fleet made up of a missile destroyer, a missile escort ship and an ocean-going combined supply ship in the Western Pacific and other waters on May 25.

Observers predict that the military stand-off between the two countries will get more serious in the days ahead.
