Days after a deadly border clash with China, Indian Prime Minister Narendra Modi said late Friday that Chinese troops did not enter the Asian nation’s territory "nor is any of our post captured." 

During a virtual meeting with political parties, Modi assured opposition leaders that Indian borders are secure and the military is capable of mounting a defense.

“Neither anyone has intruded into our territory nor taken over any post," Modi said, adding that Indian "forces are doing what they have to do to protect the country, whether it is deployment, action or counter-action."

"Our patrolling capacity has increased due to newly built infrastructure, especially along the LAC," Modi said, referring to the Line of Control, a defacto border between India and China.

His statement came after a Chinese Foreign Ministry spokesman said its Chinese military did not cross the border during a skirmish Monday that killed at least 20 Indian soldiers along the border in the Ladakh area of the disputed Jammu and Kashmir region.

Modi said India wants peace and friendship, but upholding sovereignty is foremost.

He highlighted the government has given primacy to the development of the border area infrastructure to make the borders more secure.

“Provision has also been made for fighter planes, modern helicopters, missile defense systems and other such needs of our forces. Through the recently developed infrastructure, patrolling capacity at the LAC has also increased,” he said.

Main opposition Indian National Congress party leader Sonia Gandhi said leaders are still in the dark about details and questioned the government about intelligence reports and related matters.

China accuses Indian troops entered its territory

Earlier Friday, Chinese Foreign Ministry spokesman Zhao Lijian said the Galwan valley in the Ladakh area is “located on the Chinese side" of the defacto border, and accused Indian troops of crossing the line Monday night and "trespassed into China's territory."

“Indian border troops have unilaterally and continuously built roads, bridges and other facilities at the LAC in Galwan valley.”

However, he said civil and military officials of the two sides maintained communication including a commander-level meeting June 6 to “ease the situation.”

“In response to strong demand of Chinese side, India agreed to withdraw personnel who crossed LAC and demolish the facilities, and so they did,” Zhao claimed.

“The Indian side promised that they would not cross the estuary of the Galwan river to patrol and build facilities and the two sides would discuss and decide phased withdrawal of troops through the meetings between commanders on the ground,” he said.

Border tensions between the two countries have existed for more than seven decades.

China claims territory in India's northeast, while New Delhi accuses Beijing of occupying its territory in the Aksai Chin plateau in the Himalayas, including part of the Ladakh region.
