NEW DELHI -- India's army chief visited the border with China in the Himalayan region to review his troops' preparedness after hand-to-hand combat between Indian and Chinese soldiers left 20 Indians dead earlier this month, the army said Thursday.
The trip by Gen. M.M. Naravane to the Ladakh region on Wednesday and Thursday came as two Indian security officials reported that Chinese soldiers have entered Indian-controlled territory in another strategically important area despite ongoing talks between military commanders and diplomats to ease tensions.
Both officials spoke on condition of anonymity because of the sensitive nature of the information and in keeping with government policies. The Indian army has not commented on the reported incursion.
The officials said Chinese troops had advanced in the Depsang Plains, also in Ladakh, in violation of border management and jointly agreed patrolling protocols between the two countries.
Depsang is a strategically important area close to Daulat Beg Oldie, where India in recent years made an airstrip close to China operational.
The Indian officials said a similar Chinese entry in the area took place in 2013, but the two sides resolved it through diplomatic channels.
An army tweet said Naravane visited "forward areas in eastern Ladakh and reviewed operation situation on the ground."
The Indian officials said the current standoff began in early May when large contingents of Chinese soldiers entered deep inside Indian-controlled territory at three places in Ladakh, erecting tents.
They said the soldiers ignored repeated verbal warnings, triggering a yelling match, stone-throwing and even fistfights in at least one place along Pangong Lake, the site of several such confrontations in the past.
The Galwan Valley, where the clash occurred, falls within a remote stretch of the 3,380-kilometre (2,100-mile) Line of Actual Control -- the border established following a war between India and China in 1962 that resulted in an uneasy truce.
On Thursday, Indian External Affairs Ministry spokesman Anuag Srivastava accused Chinese forces of acting in disregard of agreements between the two countries. He said China's deployment of a large number of troops and "unjustified and untenable claims" on the Galwan Valley were examples of the changed behaviour.
"At the heart of the matter is that since early May the Chinese side has been amassing a large continent of troops and armaments along the Line of Actual Control,? he said in a statement.
"Obviously, the Indian side had to undertake counter-deployments and resulting tension thereafter expressed itself," he said.
Rahul Bedi, a defence analyst, said that despite claims of mutual disengagement, tensions between Indian and Chinese forces are still high.
"India is trying to match China's military assets in the region. The Chinese have ingressed disputed areas where both sides are trying to manoeuvr the situation to their advantage," Bedi said, adding that he didn't see a quick end to the crisis.
China on Wednesday again accused India of provoking the border clash, but urged New Delhi to "meet China halfway" in restoring peace and stability along their disputed frontier.
Indian and Chinese military commanders agreed on Monday to disengage their forces in their first meeting since the confrontation.
The clash was the deadliest between the two countries in 45 years. India said 20 of its soldiers died. China has not released any information on casualties on its side.
Soldiers brawled with clubs, rocks and their fists at 4,270 metres (14,000 feet) above sea level, but no shots were fired, Indian officials have said. The soldiers carry firearms but are not allowed to use them under a previous agreement in the border dispute.
Indian security officials said the fatalities were caused by severe injuries and exposure to subfreezing temperatures.
