China urged India to pull back its border guards that have crossed into Chinese territory from the Sikkim section of the China-India border. 

Recently, Indian border guards have "obstructed normal activities" of Chinese frontier forces in the Donglang area, and China has taken counter-measures and made a thorough investigation of this matter, Chinese Foreign Ministry spokesman Geng Shuang said at a regular press conference in Beijing on Monday.

India should respect China's territorial integrity to maintain peace and stability as well as the border treaties signed by the two countries, Geng said, noting that the Indian government has repeatedly confirmed in writing that there is no objection to the treaties.

In view of the above event, for safety reasons, Geng confirmed that China has informed India through diplomatic channels that it has to put off arranging the Indian official pilgrims to enter China at the Nathu La Pass.

The Nathu La Pass sits 4,545 meters above sea level and is wedged between Yadong County in Xigaze Prefecture, Tibet Autonomous Region, and India's Sikkim State.
