WASHINGTON, April 10 (Reuters) - U.S. Trade Representative Jamieson Greer said on Friday that ‌the United States is trying to maintain ‌a stable relationship with China, but if Beijing gets ​involved with Iran in a way that is counter to U.S. interests, that would complicate matters.

"The underlying goals of our economies are ‌so different. But ⁠there's a way where we can have some economic stability. If ⁠China is going to be involved in Iran in a way that's harmful to U.S. ​interests, then ​that obviously complicates ​it, and that's China's ‌responsibility to eliminate that," Greer said in an interview on CNBC.

Greer also said he expects President Donald Trump to have a good meeting next month with Chinese President Xi ‌Jinping. The trip comes ​just a year after Washington ​rolled out ​sweeping and at times erratic global ‌tariffs.

"I think the thing to ​remember with ​China is, although we're trying very hard to have stability with China, particularly ​in trade ‌and economics, not every challenge with them ​is resolved," Greer said.
