BEIJING, July 24 (Xinhua) -- China Monday urged India to immediately withdraw all troops that have illegally entered China, stating that the nation would defend its territorial sovereignty "at all costs."

"The Chinese border troops have taken initial counter measures at the site and will step up targeted deployment and training," said Wu Qian, spokesperson for the Ministry of National Defense at a press conference.

Indian troops crossed the China-India boundary into Chinese territory in mid-June to obstruct road construction in Donglang region.

Wu urged India to immediately withdraw it troops, describing the request as a prerequisite to resolving the situation.

"We strongly urge India to take solid measures to correct its mistakes and desist from provocation," Wu said, calling for a joint effort to maintain peace in the border areas.

The spokesperson warned India to abandon any impractical illusions.

The history of the People's Liberation Army (PLA) in the past 90 years has demonstrated its increasing capacities and unshakable determination to safeguard national sovereignty and territorial integrity, he said.

"It's easier to shake a mountain than the PLA," Wu said.
