The chief US delegate to the International Atomic Energy Agency says a deal allowing UN monitors to inspect some of India's nuclear facilities is a net gain for global nonproliferation. Gregory L. Schulte said Wednesday the agreement between India and the UN nuclear watchdog was sound. IAEA approval of the so-called safeguards agreement is one of several steps needed to finalize a nuclear deal between India and the US. The agency's 35-member board of governors will consider the matter Friday. Schulte said Wednesday that approval would constitute a major step forward in the effort to erase differences that impeded the world's relationship with India for more than three decades.
