WASHINGTON (AP) - Pakistan s foreign secretary is ruling out sharing atomic weapons with Saudi Arabia as world powers and Iran near a possible nuclear agreement.

Aizaz Ahmad Chaudhry says any such speculation is "unfounded and baseless."

He says the nuclear arsenal is solely for Pakistan s national security, and Pakistan won t sell or transfer weapons or advanced technology.

Chaudhry spoke to reporters as he finished a Washington visit Thursday. He was asked about concerns that Saudi Arabia and other Arab countries could seek nuclear capabilities to match Iran s.

Pakistan has long been among the world s greatest proliferation threats, having shared weapons technology with North Korea, Iran and Libya.

But Chaudhry says his country has cracked down hard in recent years.
