China and the United States, as the world's largest developing country and developed country, respectively, should strengthen communication and handle differences properly, said Chinese Vice President Han Zheng on Wednesday.

Han made the remarks while meeting with heads of U.S. friendly groups, think tanks and people from all walks of life on the sidelines of the UN General Assembly in New York.

Han called on the two sides to follow the three principles of mutual respect, peaceful coexistence and win-win cooperation put forward by Chinese President Xi Jinping and implement the important consensus reached by the two heads of state in Bali, Indonesia.

He also urged efforts to enhance China-U.S. cooperation fields such as economy, trade and people-to-people exchanges to boost the healthy and stable development of China-U.S. relations.

Noting the Chinese economy is recovering and transitioning from high-speed growth to high-quality development, Han told U.S. participants at the meeting that China pays great attention to the growth of economic volume and even greater attention to boosting the quality and efficiency of its economic growth.

China will unswervingly pursue opening up at a high level, seek win-win cooperation with other countries and provide a constant driving force for world economic recovery and growth while offering mutually beneficial cooperation opportunities for investors worldwide, he said.

Commending China's pursuit of green, low-carbon and sustainable development, participants from the U.S. side expressed hope that the U.S. and China will maintain contact and personnel exchanges at all levels and promote the steady development of U.S.-China relations, adding that they are willing to continue to work toward this end.
