The UN nuclear energy agency has decided to not refer South Korea to the Security Council over the country's failure to report past nuclear experiments.
But the International Atomic Energy Agency (IAEA) said on Friday it will issue a statement of rebuke over the tests, which produced small amounts of weapons-grade uranium and plutonium in 1982 and 2000.
Meanwhile, the IAEA is also deciding whether to refer Iran to the United Nations Security Council for possible sanctions over its nuclear activities.
Iran again pledged to freeze its uranium enrichment program and honor a draft agreement with the European Union designed to avoid possible UN sanctions.
President Bush today welcomed the work of the EU, but said any nuclear suspension deal with Iran must be -- in his words -- "verifiable."
On Thursday, Tehran said it wanted to exempt 20 sensitive centrifuges from the accord, a move western diplomats said would be unacceptable.
