US President George W Bush will meet Pakistani President Asif Ali Zardari in New York on Tuesday as the two countries try to defuse tension over US military strikes in Pakistan.
The United States has reportedly launched airstrikes in Pakistani territory against Taliban and Al Qaeda militants who seek refuge in the country to launch attacks against US and NATO forces in Afghanistan.
Pakistan's government has accused Washington of violating its territory. US officials have not publicly discussed any operations inside Pakistan but have said the two countries cooperate closely in the war on terrorism.
The United States has been frustrated by Pakistan's ineffectiveness at rooting out the militants in the remote tribally governed area along the porous border region.
Bush and Zardari will meet on the sidelines of the UN General Assembly, the White House said.
