Kuwait : US-allied Kuwait called on Iran and the West to resolve a conflict over Tehran's nuclear ambitions peacefully.

Kuwait is deeply concerned about the prospect of war in the Gulf and threats by Iran to impose shipping controls in the Strait of Hormuz if it is attacked. About 40 per cent of global oil exports leave the Gulf via the waterway off Iran's southern coast.

"We hope things will not develop for the worse, and that the language of reason and dialogue between all parties prevails," Crown Prince Shaikh Nawaf Al Ahmad Al Sabah told daily Al Rai in an interview.

"We think diplomacy is the best solution."

The Crown Prince repeated previous Kuwaiti assertions that the country from where 2003's US-led invasion of Iraq was launched will not aid any military action against Iran.
