Washington (Agencies): The US has denied reports that it has suspended all high-level dialogue with Pakistan after Islamabad refused to discharge an American diplomat detained on possible murder charges.

"We continue contact with Pakistan to express the importance of resolving the case of a US diplomat in accordance with international law," State Department spokesman PJ Crowley wrote in Twitter.

Crowley's tweet came hours after The Washington Post reported that Secretary of State Hillary Clinton cancelled a meeting last weekend with Pakistani Foreign Minister Shah Mehmood Qureshi at an international security discussion in Munich, in disapproval of the arrest of its diplomat Raymond Allen Davis.

"Not true… We continue to meet with Pakistani officials and press for our diplomat's release," a senior administration official said when asked about news items published in various media.

The Trilateral Ministerial is presently scheduled for February 23 to 24. Preparations for it continue, the official added.

"We continue high-level contacts with Pakistani government to make plain that our US diplomat should be released. He has diplomatic immunity.

"Pakistan has international obligations under the Vienna convention and we continue to stress that to the Pakistani government at all levels," Crowley said.
