CNN News:英国首相梅访美会晤特朗普 墨西哥总统取消与特朗普的会面

Yesterday, British Prime Minister Theresa May came to the U.S. for a two-day visit. She's the first serving foreign leader to speak at the annual congressional Republican retreat. That's in Philadelphia this year. And Prime Minister May is also the first foreign leader to meet with U.S. President Donald Trump since his inauguration. Britain is widely considered to be America's closest ally.

A separate international meeting was cancelled though. Mexican President Enrique Pena Nieto had been scheduled to visit President Trump at the White House next Tuesday. But Mr. Trump's moving forward with plans to build a wall on the U.S. Mexico border. He wants Mexico to pay for it and that's something Mr. Pena Nieto has repeatedly said Mexico would not do.
On Thursday, President Trump said if President Pena Nieto continued to refuse to finance the wall, it would be better for him to skip the meeting.
So, the Mexican leader cancelled his plans, saying his country does not believe in walls. The White House said it would keep communication open with America's southern neighbor.
