China welcomes and supports all efforts conducive to the realization of peace on the Ukraine crisis, a spokesperson for the Chinese Ministry of Foreign Affairs said on Friday in comments over a Ukraine peace conference to be held in Switzerland over the weekend.

China's position on the conference has been fair, just and open, said Lin Jian at a press briefing.

Lin said China has also maintained close communication with all parties concerned, including Switzerland and Ukraine, on the organization of the conference and encouraged the invitation of all parties to participate on an equal footing and to discuss all options in a fair manner.

The Chinese side has said it would not take part in the meeting, saying that it seems the meeting has yet to meet the three important elements, which are recognition from both Russia and Ukraine, equal participation of all parties and fair discussion of all peace plans.

China and Brazil issued a six-point agreement on the political settlement of the Ukraine crisis on May 23.

The two countries have called on relevant parties to observe three principles for deescalating the situation: no expansion of the battlefield, no escalation of fighting or provocation by any party, maintaining dialogue and negotiation, and increasing humanitarian assistance.

In the six-point common understandings, China and Brazil also expressed opposition to the use of weapons of mass destruction, attacks on nuclear power plants, or dividing the world into isolated political or economic groups.

More than 100 countries have responded positively to the common understandings, which reflect the general expectations of the international community, said Lin on Friday.

"We welcome more countries to support and endorse the six-point common understandings," he said.
