MOSCOW, Nov. 25 (Xinhua) -- China-Russia relations are always put at the central place of Chinese diplomacy, and China has an unwavering determination to deepen all-round cooperation with Russia, Chinese Deputy Foreign Minister Le Yucheng said Monday.

There is no limit for the development of China-Russia relations, Le said in Moscow during talks with Russian Foreign Minister Sergei Lavrov.

China is looking forward to the visit of Russian President Vladimir Putin to China next year, he said.

Bilateral trade stood at nearly 90 billion U.S. dollars in the first 10 months of this year, and the China-Russia east-route natural gas pipeline will be put into operation in early December, Le said.

The Tongjiang-Nizhneleninskoye cross-border railway bridge and the Heihe-Blagoveshchensk cross-border highway bridge are about to open to traffic, he added.

The "China-Russia duo" brings stability and certainty to a changing world, and the prospects for bilateral relations are enormous, Le said.

Lavrov said Le's visit would be conducive to better strategic coordination between the Russian and Chinese foreign ministries so that the two countries can provide more solutions to preserving the international order on the basis of the UN Charter and the norms of international law and opposing unilateralism and hegemonism.
