BEIJING,Oct10: China on Tuesday claimed that India had built facilities on its side of the Sikkim border in violation of the bilateral agreement on maintaining peace in the region. The claim came a day after Indian government sources said the Chinese army personnel recently demanded removal of two bunkers on the border in Sikkim, which was outrightly rejected. "The facilities built by India on the Chinese side of the border line are in violation of the agreement between China and India on maintaining peace and tranquillity in the border region," Chinese Foreign Ministry spokesman, Liu Jianchao, said here. The spokesman confirmed that China had requested India to remove the facilities. He also rejected as groundless reports that Chinese troops have made incursions into Bhutan. Indian government sources had said that Chinese army personnel kept on transgressing at certain places along the Line of Actual Control (LAC) in an attempt to assert their claim on certain Indian territories. "We (India and China) have different perceptions of LAC ... We know where the differences are," the sources said, adding the issue was being addressed in the ongoing talks on boundary question. Interestingly, the Chinese army's demand for removal of the bunkers came a week after Chinese official media reported that the Sino-India boundary area was growing more amicable with the militaries of both sides ready to resolve problems, including incursions.
