Meanwhile, Huawei chairman Guo Ping lashed out at the US while presenting at MWC , saying it has "no evidence, nothing," that the firm spied on behalf of the Chinese government. It used the tech show to parade its 5G network ambitions, including debuting its foldable 5G phone, the Mate X.
Its lobbying efforts have been met with mixed success. Here is a run-down of how allies have reacted.

A major US ally, the UK continues to voice concerns about Huawei, but may still decide to use its 5G equipment.
The Financial Times reported last month that the British government decided it could "mitigate the risks" associated with using Huawei's 5G technology.
On Monday, Jeremy Fleming, the head of the UK's cybersecurity agency GCHQ, said the UK had not yet made a decision on integrating the firm's tech into networks.
"We have to understand the opportunities and threats from China's technological offer, understand the global nature of supply chains and service provision irrespective of the flag of the supplier (and) take a clear view on the implications of China's technological acquisition strategy in the West," Fleming said at a summit in Singapore, as reported by CNBC .
"We will invest even more in the UK. Because if the US doesn't trust us, then we will shift our investment from the US to the UK on an even bigger scale," he said.
Germany
Several unnamed German officials told The Wall Street Journal earlier this month that Germany was leaning towards allowing Huawei to take part in building 5G networks in the country.
Officials told the Journal that the agreement was preliminary, and still had to be approved by the full cabinet and Parliament, which won't happen for several weeks.
Japan
India
A Wall Street Journal report on February 21 suggested that the US is not having much luck in convincing India to freeze Huawei out.
"Huawei is today at the frontier on 5G and so can't be ignored," an unnamed Indian official told the Journal. The same official added that India would select 5G vendors on its own terms, "not under pressure" from the US.
India is a rapidly expanding online market, and will be a major win for Huawei if it can start selling its 5G kit in the country, and conversely a huge blow to the US.

In November 2018, New Zealand blocked Huawei's 5G technology . Its intelligence agency shot down a proposal from one of the country's biggest telecom carriers Spark to use Huawei equipment in its 5G network, citing "significant security risks."
In February, Huawei reacted by taking out full-page ads in New Zealand newspapers saying "5G without Huawei is like rugby without New Zealand," trying to draw a parallel between its own 5G tech and New Zealand's All Blacks rugby team.
Most recently, it seems New Zealand could be persuaded to let Huawei in. Prime Minister Jacinda Ardern said in mid-February that the door was not totally shut, saying there's not yet been a "final decision."
"It is now currently with Spark to mitigate the concerns that have been raised. That is where the process sits," she said.
