Huawei denies wrongdoing after US criminal charges

Huawei is the world's second biggest smartphone maker by volume

Chinese telecoms giant Huawei has denied any wrongdoing after US prosecutors filed a host of criminal charges against the firm.

Huawei has also rejected criminal claims against its chief financial officer Meng Wanzhou, who was arrested in Canada last month.

The charges filed against Huawei in the US include bank fraud, obstruction of justice and theft of technology.

The case could escalate tensions between China and the US.

In a statement, Huawei said it was "disappointed to learn of the charges brought against the company today".

It said it did not commit "any of the asserted violations" and that it "is not aware of any wrongdoing by Ms Meng".

The statement said the allegations of stealing trade secrets were the subject of a settled civil suit, in which a jury found "neither damages nor wilful and malicious conduct".

What are the charges?

The indictment, announced on Monday, alleges Huawei misled the US and a global bank about its relationship with two subsidiaries, Huawei Device USA and Skycom Tech, to conduct business with Iran.

US President Donald Trump's administration has reinstated all sanctions on Iran removed under a 2015 nuclear deal and recently imposed even stricter measures, hitting oil exports, shipping and banks.

A second indictment alleges Huawei stole technology from phone company T-Mobile used to test smartphone durability, as well as obstructing justice and committing wire fraud.

Huawei said it settled the dispute with T-Mobile in a civil case filed in 2014.

The firm's technology, known as Tappy, mimicked human fingers to test phones.

In all, the US has laid 23 charges against the company.

"These charges lay bare Huawei's alleged blatant disregard for the laws of our country and standard global business practices," said FBI Director Christopher Wray.

Mr Wray said companies like Huawei "pose a dual threat to both our economic and national security".

At a briefing in Beijing, government spokesperson Geng Shuang said there were "political motivations" behind US attempts to "smear and suppress certain Chinese companies".

"We urge them to treat Chinese enterprises in a fair and just way."

What's the context?

Huawei is one of the largest telecommunications equipment and services providers in the world, recently passing Apple to become the second biggest smartphone maker by volume after Samsung.

But the US and other Western nations have been concerned that the Chinese government could use Huawei's technology to expand its spying ability, although the firm insists there is no government control.

The arrest of Ms Meng, the daughter of Huawei's founder, infuriated China.

She was arrested on 1 December in Canada's western city of Vancouver at the request of the US.

She was later granted a C$10m (£5.7m; $7.6m) bail by a local court. But she is under surveillance 24 hours a day and must wear an electronic ankle tag.

Chinese 'national champion' faces US justice

Huawei is what the Chinese call a national champion. A private firm, tasked with China's ambitions to go into the world and lead the way.

But now the full force of the US justice system is being hurled at the firm.

The allegations by the US Department of Justice are the most serious Huawei has ever seen, and go to the heart of the trade war between China and the US.

Huawei has consistently denied the allegations, and the firm's boss says it is being used as a pawn in power games between the US and China.

While the US says the charges against Huawei aren't about trade war, it is unlikely the Chinese will see it the same way.

The charges come as the US and China prepare to hold high-level trade talks in Washington this week.

US commerce secretary Wilbur Ross stated that the Huawei charges were "wholly separate" from ongoing trade negotiations with China.

However, the indictment focuses on the alleged theft of US technology, which has been a major sticking point in trade negotiations.

President Trump's administration has imposed tariffs on $250bn (£190bn) worth of Chinese goods, prompting Beijing to respond with its own tariffs.

Both countries agreed last month to suspend new tariffs for 90 days to allow talks.
