Pakistan is turning to Saudi Arabia for financial aid to ease an economic crisis that already has forced the militancy-wracked South Asian nation to start talks with the International Monetary Fund. President Asif Ali Zardari arrives Tuesday in the oil-rich Arab nation to request a deferral on oil payments and other possible support, the Foreign Ministry said. Another potential topic: negotiating with the Taliban. Analysts said Zardari's visit could yield some temporary relief, but that he was unlikely to return with a package that would render moot politically unpopular IMF aid. Economist Muzammil Aslam predicted Zardari would ask for $3 billion in deferred oil payments from the Saudis, but warned that Pakistan should prepare for IMF assistance. "If you miss the IMF now, you will need it again some months later, and that time you will have to accept more tough conditions,'' he said. Pakistan hopes that its front-line role in the war on terrorism will nudge its allies to prevent its economic downfall. But Saudi Arabia, the U.S. and other nations may condition any aid they give on Pakistan submitting to an IMF package, which would come with strict spending rules, said Shahid Hasan Siddiqui, a top economist. Pakistan Finance Ministry chief Shaukat Tareen has said that if he does not get indications of a forthcoming bailout from allies by Nov. 10 "there is no other option but to go to the IMF.''
