DUBLIN, April 30 (Reuters) - The head of the world's

largest aircraft leasing company, AerCap ( AER ), said tariffs

on aircraft between China and the United States are not having a

significant impact yet but that "it's very early in the game."

CEO Aengus Kelly added in a call with investors that he

understood that discussions are ongoing in China between

airlines and regulators that will hopefully lead to aviation and

aerospace being exempted form tariffs.
