Washington, (Agencies): US has maintained that reports about suspending all contacts with Pakistan were "not true", but hinted that the trilateral meeting involving Islamabad may be postponed if the stalemate over the release of an American diplomat detained on possible murder charges continued.

"We want to have a productive meeting. If there's a reason why we don't think the meeting will be productive we're prepared to make adjustments. If we do make those decisions, we'll let you know," State Department spokesman P J Crowley said.

Crowley was responding to a question about the postponement of the Feb 23-25 US-Afghanistan-Pakistan meeting scheduled in Washington.

The meeting is scheduled to be held at the ministerial level with Secretary of State Hillary Clinton, leading the American delegation.

"Planning is continuing for the trilateral meeting at the end of this month. It is currently scheduled to be at the ministerial level. If we make any changes in that, we'll let you know," he said.

Crowley reiterated the US demand that Pakistan release Raymond Allen Davis, who has been arrested on murder charges.

"I'm not sure that it is a correct statement. I know there are lots of things that are put out, you know, by 'unnamed official'.

"The fact is that we did notify Pakistan of this diplomat's arrival and his status. And we do not believe that there's any ambiguity about that," he said, when asked whether Pakistanis apparently do not accept the fact that Davis has diplomatic immunity.

Crowley denied reports that the Obama Administration had suspended high-level talks with Pakistan.

The reports that we have suspended all contacts withthe Pakistani government are not true. We continue to have high-level contacts with both in Pakistan and here to be able to express to them the importance that we attach to resolving this issue and this case. And we'll use every opportunity in our engagement with the Pakistani government to reiterate that position," he said.
