【正确答案】Entering the 21st century, the world has continued to undergo profound changes. Peace and development remain the calling of our times. On the other hand, factors causing instability and uncertainty are increasing and new challenges and threats are looming. Against this backdrop, the common interests between our two countries are increasing and the areas of our cooperation widening. Global peace and security now face new challenges, such as fighting international terrorism, preventing the proliferation of weapons of mass destruction, protecting the environment and human habitat and combating transnational crimes. And it is exactly in these fields that we share important strategic interests. China has a huge market and its development has generated strong demand, while the United States has advanced technology and high quality products. This has created enormous opportunities for economic and technical cooperation between our two countries. Indeed, there is a broad prospect for the growth of constructive and cooperative China-U.S. relations in all fields.
