Meanwhile, the president continues to fight for a level playing field with America's trading partners - but not everyone agrees with his aggressive approach to free and fair trade.
Trump said he is doing this in the national interest. Its central bank is allowing China's tightly controlled currency to drift lower against the dollar, a move that could help Chinese exporters.
President Donald Trump on Friday said monetary-policy tightening "hurts all that we have done", suggesting a belief that higher borrowing costs undermine the economy's gains.More news: Spider-Man PS4 Pro and PS4 are simply unbelievable
Trump has imposed tariffs on goods from several countries to try to get better trade terms for the United States.
The Fed hiked interest rates twice this year, and plans to raise them two more times by the end of 2018.
That would equal the amount of annual Chinese exports to the US for the year.
In February, Jerome Powell, Trump's hand-picked choice, became Fed chairperson. "But at the same time I'm letting them do what they feel is best", Trump said.
Presidents have historically avoided criticizing the Fed, which is created to be independent from political interference.

U.S. central bankers project two more interest rate increases this year and another three in 2019. While the Fed has raised rates, they remain low on a historical basis. In addition to Trump's comments to CNBC, Larry Kudlow, the president's top economic adviser, also told Fox Business last month he hoped the Fed raised rates "very slowly".
"The Fed's independence from short-term political pressures is critical to enabling it to take the longer-run perspective that is essential for achieving its legislated dual mandate for jobs and price stability", said Donald Kohn, a former Fed vice chairman who is now a senior fellow at the Brookings Institution in Washington.
The Fed has been slowly raising interest rates since December 2015 in an effort to avoid overheating the US economy.
Earlier today Trump threatened to unleash significant tariffs on all $500bn of Chinese imports to the US.
He also said that higher interest rates will strengthen the USA dollar too much, putting the United States at a "disadvantage" while central banks in Europe and Japan keep rates low.
He added, "No one in the administration has said anything to me that really gives me concern on this front". "So somebody would say, 'Oh, maybe you shouldn't say that as president".More news: The Open Championship Leaderboard is Stacked After the Second Round
