China's envoy to India today said his country "cannot stand another Doklam incident" and also pitched a trilateral summit between India, China and Pakistan on the sidelines of the Shanghai Cooperation Organisation or SCO. "We cannot stand another Doklam, we need to control, manage, narrow differences through expanding cooperation. The boundary question was left over by history. We need to find a mutual acceptable solution through Special Representatives," said Ambassador Luo Zhaohui, speaking at a seminar in Delhi.
