Washington, Sep 24 (IANS): Chinese President Xi Jinping has commended Boeing's long and productive cooperation with China and urged the aircraft maker to lift the partnership to higher levels.

In a tour of the Boeing Company's commercial airplane factory in Everett, Xi noted that Boeing's cooperation with China "has transcended time and achieved win-win results," serving as a "prototype" for China-US economic and trade cooperation, reports news agency Xinhua.

Pointing out that a sound China-US relationship helps foster better conditions for the US businesses to cooperate with Chinese peers, Xi encouraged Boeing to further boost cooperation with China and make more contributions to the economic cooperation and overall relations between the two countries.

China's development, he said, will create more opportunities for American companies and open new space for ever closer, win-win cooperation between Chinese and the US businesses.

Accompanied by Ray Conner, president and CEO of Boeing Commercial Airplanes, Xi walked around the factory's assembly workshop with great interest and asked about the aircraft maker's efforts on energy saving and emissions reduction, as well as its design ideas of future planes.

He also boarded a 787 plane which will soon be delivered to China's Xiamen Airlines, and spoke with Boeing employees working on it.
