BUENOS AIRES, May 21 (Xinhua) -- China has always regarded Saudi Arabia as a priority in its Middle East diplomacy as well as an important cooperation partner in the Belt and Road construction, Chinese State Councilor and Foreign Minister Wang Yi said here on Monday.

China and Saudi Arabia are all-round strategic partners, enjoying mutual understanding, mutual support and mutual trust, Wang said when meeting Saudi Foreign Minister Adel bin Ahmed al-Jubeir during the ministerial meeting of the Group of 20 (G20) in Buenos Aires, capital of Argentina.

The two countries' heads of state have established good contacts and friendship, which plays an important leading role in the development of bilateral relations, he said.

The Chinese foreign minister hoped the two sides will launch and give full play to their high-level joint committee at an early date and advance bilateral cooperation in such areas as production capacity, investment, energy, trade and infrastructure.

He also said that China is willing to work together with Saudi Arabia for the success of the China-Arab States Cooperation Forum scheduled for July and further boost solidarity and cooperation with Arab countries.

China would keep contacts with Saudi Arabia over the Middle East issues and will always side with Arab countries and safeguard their just rights and interests as well as peace and stability in the Middle East, Wang said.

Jubeir said China is Saudi Arabia's important strategic partner, and that the two sides enjoy mutual trust and have conducted frequent high-level contacts, with abundant achievements scored in bilateral exchanges and cooperation in various fields.

Saudi Arabia is willing to participate in the Belt and Road cooperation, and hopes the two sides will further implement the consensus reached by the heads of state of the two countries as well as the agreements signed between the two countries, and step up pragmatic cooperation in such areas as ports and energy, Jubeir said.

Saudi Arabia welcomes more Chinese enterprises to carry out investment and cooperation, Jubeir added.
