NEW DELHI -- The defence ministers from India and China have met in the Russian capital as the two sides try to lower tensions along their disputed border in the eastern Ladakh region, where a June clash killed 20 Indian soldiers.

At the meeting Friday with China's Gen. Wei Fenghe, India's Rajnath Singh said that 鈥渢he current situation should be handled responsibly and neither side should take any further action that could either complicate the situation or escalate matters in the border areas,鈥� the Indian defence ministry said in a statement.

Singh also said that amassing of large number of Chinese troops, their aggressive behaviour and attempts to unilaterally alter the status quo were in violation of existing bilateral agreements, according to the statement.

It was the first high-level direct contact between the two sides since the standoff erupted months ago in the Karakorum mountains. The foreign ministers and other officials of the two countries have been speaking over the phone since the standoff started in May.

The ministers met on the sidelines of a gathering of the defence chiefs of the Shanghai Cooperation Organization. The body comprises China, India, Pakistan, Russia, Kazakhstan, Krgyzstan, Tajikistan and Uzbekistan.

India's External Affairs Ministry said the meeting took place at the Chinese defence minister's request.

鈥淧eace and security in the region demands a climate of trust, non-aggression, peaceful resolution of differences and respect for international rules,鈥� Singh said at the meeting.

Wei told Singh the sides should 鈥渃ool down鈥� the situation and 鈥渕aintain peace and tranquility,鈥� the Chinese Ministry of Defence said on its website. However, it said responsibility for the tensions 鈥渓ies completely with India.鈥�

鈥淣ot one inch of Chinese territory can be lost,鈥� the Ministry of Defence said.

India's Defence Ministry said in a tweet that Singh conveyed to his Chinese counterpart that 鈥渢he two sides should continue their discussions, including through diplomatic and military channels, to ensure complete disengagement and de-escalation and full restoration of peace and tranquility along the LAC (Line of Actual Control) at the earliest.鈥�

The tweet came as local Indian and Chinese military commanders met for a sixth straight day Saturday at a border post to iron out differences in the Chushul area in Ladakh, where new flash points emerged last week, said a top military officer, who spoke on condition of anonymity because he was not authorized to talk to reporters. He did not provide any details.

The disputed 3,500-kilometre (2,175-mile) border between the world's two most populous countries stretches from the Ladakh region in the north to the Indian state of Sikkim. The latest standoff is over portions of a pristine landscape that boasts the world's highest landing strip and a glacier that feeds one of the largest irrigation systems in the world.

Both sides accuse the other of provocative behaviour including crossing into each other's territory this week, and both have vowed to protect their territorial integrity.

India's army chief, Gen. M.M. Naravane, visited the region Thursday and Friday and met with soldiers deployed in difficult terrain above 4,300 metres (14,000 feet), the Indian Ministry of Defence said.

India said its soldiers thwarted movements by China's military last weekend. China accused Indian troops of crossing established lines of control.

The two nations fought a border war in 1962 that spilled into Ladakh and ended in an uneasy truce. Since then, troops have guarded the undefined border area, occasionally brawling. They have agreed not to attack each other with firearms.

Rival soldiers brawled in May and June with clubs, stones and their fists, leaving 20 Indian soldiers dead. China reported no casualties.

Both sides have pledged to safeguard their territory but also try to end the standoff, which has dramatically changed the India-China relationship. Several rounds of military and diplomatic talks on the crisis have been unsuccessful.
