Armitage and Rocca are arriving here on Thursday to meet President Pervez Musharraf and other top leaders, Pakistan Foreign Office spokesman Masood Khan told reporters on Tuesday.

The ongoing war on terrorism, deteriorating Pak-Afghan relations over the issue of resurgence of Taliban, the progress on US request to send troops to Iraq would also come up for discussion.

Armitage and Rocca's visit to Islamabad may focus on relations between India and Pakistan. After the highs of stabling road links and exchange of Parliamentary delegations, which attracted large public participation on both sides, the ties showed signs of deterioration specially after strong speeches delivered by Musharraf and Vajpayee at last week's UN General Assembly.

The US officials arrive virtually days after Musharraf's meeting with US President George W Bush and US Secretary Collin Powell last week on the sidelines of UN General Assembly in New York.

Armitage and Rocca would hold talks with Musharraf to review actions taken on decisions arrived at during Pakistan President's meetings with Bush and Powell, diplomatic sources said here. Their visit coincides with the 10-day tour of Pakistan Premier Mir Zafarullah Khan Jamali to Washington, which began on Tuesday.

With escalation of violence in Kashmir, Armitage was again expected to press Pakistan to crackdown on the militant groups. This time the steps being taken by Pakistan to crackdown on Taliban too were expected to come under close scrutiny as both US and Afghanistan expressed concern over resurgence of Taliban in the recent months using Pakistan territory.
