Mumbai (PTI): Accusing the Centre of ignoring India's strategic interests, BJP President Rajnath Singh on Monday said the UPA government is soft on China due to support by Left parties.

"Yes, there is truth in what you say," Singh said when asked if the Government was soft on China owing to support extended to it by Left parties.

"A complacent UPA is helping China's strategic expansion, the BJP president told reporters. "The manner in which the UPA government is busy placating China, it has put our strategic interests in jeopardy," he said.

Singh accused the Communists of indulging in "domestic friendship" with the UPA and "international friendship with China."

The UPA government has failed miserably on both domestic and international fronts, he said. In the international arena, the government has become isolated, he added.

During the last four years, India has lost the diplomatic edge achieved by the NDA regime, Singh said.

Recent claim by China on the 'Finger Point area' in Sikkim shows China's impudence while dealing with India, he said. China had accepted Sikkim as an integral part of India when the NDA was in power, Singh said.
