NEW DELHI — Rising economic and military power is emboldening Beijing to pursue a more muscular foreign policy. Having earlier preached the gospel of its "peaceful rise," China is now beginning to take the gloves off, confident of the muscle it has acquired.

From provocatively seeking to assert its jurisdiction over islets claimed by Vietnam in the South China Sea to whipping up diplomatic spats with Germany, Canada and the United States over their hospitality to the Dalai Lama, Beijing has shown an increasing propensity to flex its muscles.

Other such recent instances include China's demolition of a few unmanned Indian forward posts at the Tibet-Bhutan-Sikkim tri-junction, its large-scale war game in the South and East China Seas, its public showcasing of new military hardware like the Jin-class, nuclear-capable submarine, its strategic moves around India, and its last-minute cancellation of a long-planned Hong Kong visit by the U.S. carrier, Kitty Hawk. Beijing also refused to let two American minesweepers enter Hong Kong harbor for shelter during a Pacific storm.
