Enhanced interactions and cooperation between China and the United States serve the interests of our two peoples and are conducive to world peace and development. We should stay firmly rooted in the present while looking ahead to the future, and view and approach China-U. S. relations from a strategic and long-term perspective. We should, on the basis of the principles set forth in the three Sino-U. S. joint communiqués, respect each other as equals and promote closer exchanges and cooperation. This will enable us to make steady progress in advancing constructive and cooperative China-U. S. relations, and bring more benefits to our two peoples and people of the world.
