WASHINGTON (Reuters) -White House economic adviser Kevin Hassett said on Thursday three trade deals were nearly done and he expected more despite a trade court ruling that blocked most of President Donald Trump's tariffs.

"There are many, many deals coming. And there were three that basically look like they're done," Hassett said in an interview with Fox Business Network.

Hassett dismissed a U.S. trade court ruling on Wednesday that blocked most tariffs and found Trump had overstepped his authority as the work of "activist judges". He said he was confident the administration would win on appeal.

The administration's view is that numerous countries will open up their markets to American products in the next month or two, Hassett said.

"If there are little hiccups here or there because of decisions that activist judges make, then it shouldn't just concern you at all, and it's certainly not going to affect the negotiations," Hassett said.

There were three deals ready for Trump's review at the end of last week, Hassett said.
