The one-km withdrawal by China at Ladakh's Galwan Valley came after special representatives of India and China agreed to disengage, "take guidance from the consensus of leaders" and "not allow differences to become disputes". National Security Advisor Ajit Doval and Chinese foreign minister Wang Yi, who had a telephonic conversation on Sunday, also agreed that both sides should "strictly respect and observe" the Line of Actual Control -- the de facto border between India and China -- and should not take any unilateral action to alter the status quo, the government said.
