US Secretary of State Hillary Rodham Clinton said Tuesday her talks with China had improved "understanding, confidence and trust" between the countries, DPA reported.
Speaking at the end of her two-day visit, she said "the Chinese fully understand the seriousness of the situation," in reference to escalating tensions between North and South Korea.
Clinton was accompanied by US Treasury Secretary Timothy Geithner, who requested that Beijing improve market access, and grant US companies the same investment conditions as Chinese ones.
US Commerce Secretary Gary Locke and Chairman of the Federal Reserve Ben Bernanke were also in China for the top-level talks.
The agenda ranged from trade and currency topics to the security issues surrounding the tensions on the Korean peninsula and the development of Iran's nuclear programme.
