U.S. President Donald Trump on Wednesday signed a legislation supporting anti-government protesters in Hong Kong.

However, some analysts say the legislation would not derail trade negotiations, as Trump's signature was expected.

"Had the President vetoed the bill, it would certainly have gone back to both houses where they would have overridden the veto," Jeffrey Halley, senior market analyst at OANDA said in a note.

Halley noted that China needed a trade agreement just as much as the U.S did, given its lagging economy.
