The Prime Minister, Mr. Atal Behari Vajpayee, today sought a high- profile role for India in regard to Afghanistan and ruled out a meeting with the Pakistan President, Gen. Pervez Musharraf, during his visit to New York later this week. Mr. Vajpayee said the Russian President, Mr. Vladimir Putin, had indicated that the existing six-plus-two mechanism on Afghanistan should be expanded and India included. He would raise the question of the U.N-sponsored mechanism during his talks with the U.S. President, Mr. George W. Bush, in Washington later this week.
