Speaking during a summit with Japanese Prime Minister Shinzo Abe, Bush said the two countries “speak with one voice” to the Tehran regime.
“Our nations have fully implemented the sanctions imposed by the UN Security Council in response to Iran’s pursuit of nuclear weapons.
“Further defiance by Iran will only lead to additional sanctions and to further isolation from the international community,” Bush said.
The US president was referring to two rounds of sanctions voted by the Security Council against Iran for refusing to halt its uranium enrichment program.
The US and key western powers believe the program is aimed at producing nuclear weapons, while Iran insists it has only peaceful intentions.
