The United States regarded the sovereignty of the Democratic People's Republic of Korea (DPRK) as a fact and it has no intention to dispatch troops or attack the DPRK, said Christopher Hill, head of the US delegation and US Assistant Secretary of State, in Beijing today.

Noting that the six-party talks is at a crucial moment, Hill said there may exist many different options to resolve the Korean Peninsula nuclear issue, but the best choice is to conduct negotiation through the six-party talks.

Avoiding problems is not a solution, he said at the opening ceremony of the fourth round of the six-party talks on the Korean Peninsula nuclear issue.

Hill said the United States has always hoped that the six-party talks could be resumed as early as possibly since the third round of the talks in June last year.

In the past year when the six-party talks was suspended, the US side had one-on-one contact with the DPRK for six times under the framework of the six-party talks, he said.

During the contacts, the US side had made clear its key stance and opinions to the DPRK, and the United States is ready for "serious" talks under the same framework, he added.
