The pledge came out of a meeting between Chinese Vice Premier Li Keqiang and First Deputy Prime Minister of Uzbekistan Rustam Azimov.
Li said the economies of the two countries are complementary. The two sides have their own unique advantages thus providing good conditions for trade cooperation.
China will make joint efforts with Uzbekistan to expand bilateral trade, deepen financial cooperation, create a sound environment for cross-border investment by companies and increase cooperation projects on energy, non-resources and infrastructure.
Azimov said he hoped the two sides would deepen cooperation in all areas, Xinhua reported.
Li also spoke highly of bilateral relations, saying China is satisfied with the current development. The upcoming China visit of President Islam Karimov will inject vitality into the relationship's future development, he said.
Azimov said the president's visit is a great event for the bilateral relationship, and that China is an intimate friend and partner of Uzbekistan.
