Top level leaders of the United States and China needed to have more exchanges with each other for the good of not only the two countries, but for the world, and U.S. law makers need to know more about the great changes in China, a top American investment banker urged Wednesday.

In an interview with Xinhua, John Mack, Chairman and Chief Executive Officer of Morgan Stanley, a leading global financial services firm, said it would be "very positive" for leaders of the United States and China to have "more interchanges of ideas" and spend more time with each other, because both countries were "extremely important" in the world.

It would be "very positive" not just for China, not just for the United States, "but positive for the world," he said, adding that the governments of the two countries "need to spend a lot more time directly with each other."

He also encouraged U.S. congressmen and senators to go and visit China to see for themselves the "great changes" that had taken place there.

"I don't know how law makers of this country can do their job without having a better understanding of the global economy and specifically great changes in what's going on in China," Mack said against the backdrop of increased trade friction between the two countries.

As for his company's presence in the Chinese market, Mack said, "we are committed as a firm," adding with some regret that Morgan Stanley should have been "much more aggressive" in China over the last five years.

"I think as we refocus now, we will work as the (Chinese) government opens up opportunities. We will be much more involved in building our own business in China," he said.
