BEIJING, July 14 -- Iran and six major countries of the world have reached an agreement in Vienna on the Islamic republic's nuclear program, reports said on Tuesday.

China has always played a constructive part in resolving the decade-long dispute, had an objective, fair and responsible attitude toward the issue, and stood ready to work with other countries to uphold international non-proliferation regime.

DIALOGUE IS ONLY WAY OUT

As a peace-loving country, China has always played a constructive role in moving forward the negotiation with a just and objective position. It opposes imposition of unilateral sanctions and use or threat of military force against Iran.

Meanwhile, China opposes Iran's attempts to develop nuclear weapons and supports the establishment of a zone free of weapons of mass destruction in the Middle East.

China hopes that all parties will implement earnestly the comprehensive agreement, maintain a good momentum of the negotiation, and uphold peace in the Middle-East region.

"China will continue to take an active part in the negotiation and will work tirelessly for a comprehensive, long-term, proper solution to Iran's nuclear issue," Chinese Foreign Minister Wang Yi said on Monday on the sidelines of the negotiation in Vienna.

FLEXIBILITY NEEDED IN NEGOTIATION

As significant differences have existed for a long time, China called on all parties to treasure the hard-earned results of the talks in the Swiss city of Lausanne, and use the Lausanne framework as the basis for new negotiations.

Meanwhile, there should not be any new demands from any party in the new talks in order to prevent further complication of the issue.

Due attention should be paid to the legitimate concerns of all parties involved and reasonable solutions should be found, he said. Besides, all sides should advance toward the same direction.

China hopes that all parties show flexibility and creativity to seek a package of solutions that takes all parties' concerns into consideration.

"China believes no agreement could be perfect,......Conditions are already in place for us to reach a good agreement," Chinese foreign minister said. "We believe that there can not and should not be a further delay of the negotiations."

In China's point of view, reaching a comprehensive agreement is conducive to safeguarding the system of nonproliferation of nuclear weapons as well as the peace and stability in the Middle East.
