China and the United States held their third round of strategic dialogue on bilateral, regional and international issues here on Wednesday.
"Hopefully the dialogue will produce positive results," Chinese Vice Foreign Minister Yang Jiechi said in the opening address.
"The United States and China have very important relationship," the US Under Secretary of State Nicholas Burns said.
"The relationship focuses on bilateral issues that motivate us from day to day, and we also have other issues....(because) together we have responsibility for global peace and global security," Burns said.
Yang and Burns co-chaired the day-long closed-door dialogue during which the two sides reportedly exchanged views on the North Korean and Iranian nuclear issues.
China is expected to press the US not to sell sophisticated arms to Taiwan under a $16 billion deal.
Beijing views Taiwan as a rebel province that must be reunified with the mainland, even by force.
Chinese Foreign Minister Li Zhaoxing and Vice Foreign Minister Dai Bingguo will meet with Burns later on Wednesday.
Two rounds of China-US strategic dialogues had been held in August and December last year.
