The U.S trade agreement with China easing sanctions on Huawei has prompted a backlash from lawmakers over national security concerns amid confusion over how the deal may affect the Chinese tech giant.

In the weekend agreement with his Chinese counterpart Xi Jinping, US President Donald Trump suggested a potentially softer position on Huawei, a sticking point in the trade war.

White House economic adviser Larry Kudlow said on Sunday that there's "a good chance" the deal will open the door to "new licences" allowing more exports to the Chinese firm suspected of working with Beijing's intelligence services to facilitate spying — a charge that the world's number two smartphone supplier denies.

In June the US government added Huawei to an "entity list" of companies barred from receiving US-made components without permission from Washington.

Some lawmakers accused Trump of selling out on national security.

“If President Trump has in fact bargained away the recent restrictions on #Huawei, then we will have to get those restrictions put back in place through legislation,” Republican senator Marco Rubio tweeted.

Democratic senator Chuck Schumer echoed those remarks, tweeting that “Huawei is one of (the) few potent levers we have to make China play fair on trade.”

“President @realDonaldTrump: This is unacceptable. Why are you backing down again on China?

“Huawei is one of few potent levers we have to make China play fair on trade.

This will dramatically undercut our ability to change China’s unfair trade practices.

“....amounts of agricultural product from our great Farmers. At the request of our High Tech companies, and President Xi, I agreed to allow Chinese company Huawei to buy product from them which will not impact our National Security. Importantly, we have opened up negotiations....”

Trump told reporters after the Osaka G20 meeting that US companies “can sell their equipment to Huawei" if there's no great security problem attached.

“Huawei is a complicated situation” that would be discussed as part of a broader trade agreement, he said, adding, “We have a national security problem, which to me is paramount.”

Republican representative Jim Banks called the deal "extremely troubling" and said it would make it harder to negotiate with China. “Why not keep #Huawei on our blacklist until China demonstrates a change in behaviour?” Banks tweeted.

Michael McFaul, a Stanford professor and former ambassador to Russia, said Trump's decision undercuts his argument about national security

“When you tell the world one day Huawei is a security threat and then reverse that argument the next day, you undermine the veracity of the initial security claim," McFaul wrote on Twitter.

It remained unclear, however, what the deal would mean for Huawei, which under US restrictions could be denied key software including much of the Google Android system and important hardware to allow it to keep making smartphones and other equipment.

Asked about the agreement, a Huawei spokesman said only: “We acknowledge President Trump's comments related to Huawei over the weekend and have nothing further to add at this time.”

Damage done

The deal "is unlikely to give Huawei the products it really needs and, even if it did, it is quite possible that fatal damage has already been done to Huawei's smartphone business," technology analyst Richard Windsor said on his Radio Free Mobile blog.

Samm Sacks, a fellow at the New America Foundation China Digital Economy project, said the US faces a difficult task in trying to resolve the trade dispute while maintaining a hard line on Huawei's national security risks.

“The problem is that Trump has given a green light to national security hardliners whose end objective has not been to find a deal in the trade war, but to create a world free of Chinese telecom equipment,” Sacks said.

One possible compromise would be to ease restrictions on Huawei's consumer business including smartphones and tablets while keeping sanctions on telecom infrastructure, which is seen as having a higher potential security risk, she said.

But Sacks noted the deal is unlikely to resolve the simmering tensions between the two economic powers over technology leadership.

“Over the longer-term, Beijing is not going to abandon its technological ambitions in artificial intelligence, internet of things, and 5G next generation networks in ways that will continue to create tension with the United States,” she said. (AFP/Business Live)
