UNITED NATIONS, Nov. 22 (Xinhua) -- China's UN envoy on Friday cited positive developments in Yemen and urged relevant parties to "seize the opportunity" to resume the political process in the war-torn country.

At a UN Security Council meeting on Yemen, Zhang Jun, China's Permanent Representative to the United Nations, said there have been signs of easing in the situation of Yemen, welcoming the signing of Riyadh Agreement on Nov. 5 between the government and the Southern Transitional Council separatists.

He said the United Nations and regional countries should seize the opportunity and further encourage the Yemeni parties to bridge their differences and strive for an early resumption of comprehensive political settlement process in Yemen.

He further said the Yemeni parties should refrain from taking actions that would lead to escalation of tensions and should keep the momentum of political solution going.

Particularly, he said, they need to demonstrate political will, stop violating the ceasefire agreement and make sure that the Hodeidah agreement is fully implemented.

The Security Council, in turn, should remain united and firmly support Yemen's sovereignty, independence, unity and territorial integrity and provide political support for the diplomatic effort of the United Nations and regional countries, he said.
