U.S. Secretary of State Hillary Clinton said on Tuesday the second round of the China-U.S. Strategic and Economic Dialogue (S&ED) had achieved a long list of agreements.

Clinton, also the special representative of U.S. President Barack Obama, made the remarks while responding to a question from Xinhua at a press conference.

"High level discussions built in an enormous amount of understanding and create an environment in which both the United States and China are able to better appreciate the other's point of view to work through in an open and candid manner the problems we are going to encounter," Clinton said.

She said the two countries' relationship had gone through a rocky period since last year, but the dialogue had improved the countries' understanding, confidence and trust in each other.

Clinton said all the signed memorandums of understanding had taken the two governments months in preparation.

She also said the bilateral natural gas project reflected the long term commitment that the countries had in each other, and that the expanded student exchange program between the two sides was a tangible result of the dialogue.
