A leading Chinese newspaper has denounced the United States and its NATO allies for conducting unilateral military operations in Asia that so far not only failed to resolve the Afghan War but also fuelled more terror activities.

An editorial in the government-controlled People's Daily charged that America's war on terror blueprint in the Afghan-Pakistan theater is basically flawed, resulting in unfortunate incidents, the latest of which is the accidental killing of Pakistani troops during a NATO airstrike.

While both U.S. and NATO officials have professed regrets over the unintended loss of lives, the publication noted that the Americans have overlooked their chief offense, brazen disregard of a nation's sovereignty.

"We must be clear that the United States and NATO have trampled on international laws and rules," Reuters quoted the People's Daily commenting.

NATO has called the incident tragic and unintended but the Chinese publication suggested that such series of strikes arrayed against a so-called ally would undermine the Pakistani government.

"Islamabad's grip on domestic security will also be weakened ... This will not only work against the war on terror, it could also leave the risk of long-term turmoil," the editorial said.

The People's Daily also warned that with events like what happened in Pakistan, America's presence in the region could serve as the best form of encouragement for the ranks of Islamist insurgents to swell.

"The risk in fighting terror this way is that it will ignite latent sympathy and support for terrorism, as well as hurting many innocent people and damaging international law," the paper said.

Thanks to U.S. and NATO military operations, the "soil nurturing terrorism will become even more fertile, and the space for terrorism to spread even broader," the newspaper commentary added.

Immediately after the incident, Pakistan shut down the supply route for U.S. forces in Afghanistan, with Pakistani officials vowing that 'no business as usual' will follow the killings of its soldiers.

Prior to the publication of the story, China's Foreign Ministry expressed shock over the attack and immediately offered assistance to neighboring Pakistan.
