U.S. President George W. Bush left Washington on Tuesday for a four-day trip to India and Pakistan.
During his three-day visit to India, Bush is expected to seal a nuclear deal with New Delhi leaders and to promote bilateral trade, officials said.
In Pakistan, Bush will ask Islamabad leaders to do more in U.S. "war on terror". He said he will also urge the Pakistani government to join hands with India to find a lasting solution to their dispute over Kashmir.
Pakistan and India have fought three wars, two over Kashmir, since their independence in 1947.
