Two of Japan's top mobile phone carriers said Wednesday they will delay releasing new handsets made by Huawei after a US ban on American companies selling technology to the Chinese tech giant.
KDDI and SoftBank Corp, the country's number two and number three carriers respectively, said the decision was taken to give them time to assess the impact of the US ban.
The country's biggest carrier, NTT Docomo, said it was also considering similar action.
SoftBank had been due to release a Huawei-made smartphone on Friday, but halted the release "because we are currently trying to confirm if our customers will be able to use the equipment with a sense of safety", company spokesman Hiroyuki Mizukami told AFP.
"We still don't know when we will be able to start selling," he said, adding the Japanese carrier is concerned about "everything" linked to the US ban.
Citing national security, US President Donald Trump has effectively banned US companies from supplying Huawei and affiliates with the critical components that have helped it grow into the world's largest supplier of telecom networking equipment and second-biggest smartphone maker.
US officials this week, however, issued a 90-day reprieve on the ban on dealing with Huawei, saying breathing space is needed to avoid huge disruption.
Japanese carrier KDDI said its release of the Huawei P30 litePremium planned in May will also be postponed, with spokeswoman Reiko Nakamura saying: "We're checking the facts on how (the US decision) was made and its impact."
NTT Docomo spokesman Takahiro Suzuki told AFP that the firm is "studying possibility of stopping the receiving of sales orders of Huawei P30 Pro that we are planning to release this summer".
Last week Trump declared a "national emergency" empowering him to blacklist companies seen as "an unacceptable risk to the national security of the United States" - a move analysts said was clearly aimed at Huawei.
The US Commerce Department also announced an effective ban on US companies selling or transferring US technology to Huawei.
Washington has long suspected deep links between Huawei and the Chinese military, and its moves against the company come amid the churning trade dispute between the world's top two economies.
The risks for Huawei came into focus this week when Google, whose Android operating system powers most of the world's smartphones, said it would cut ties with Huawei as a result of the ban.
That poses a dire threat to Huawei as loss of full access to Google's services could make its phones a hard sell to consumers.
Huawei founder says US underestimates company
Huawei founder Ren Zhengfei on Tuesday shrugged off US attempts to block his company's global ambitions, saying the United States underestimates the telecom giant's strength.
Ren spoke to Chinese media days after President Donald Trump issued orders aimed at thwarting Huawei's business in the United States, the latest salvo in a months-long effort to stop the company's charge to the top of the leaderboard in next-generation 5G technology.
"The current practice of US politicians underestimates our strength," Ren said, according to transcripts from state-run media.
"Huawei's 5G will absolutely not be affected. In terms of 5G technologies, others won't be able to catch up with Huawei in two or three years," he said.
Last week, Trump declared a "national emergency" empowering him to blacklist companies seen as "an unacceptable risk to the national security of the United States" - a move analysts said was clearly aimed at Huawei.
At the same time, the US Commerce Department announced an effective ban on American companies selling or transferring US technology to Huawei.
'Can't be isolated'
US internet giant Google, whose Android mobile operating system powers most of the world's smartphones, said this week it was beginning to cut ties with Huawei in light of the ban.
The move could have dramatic implications for Huawei smartphone users, as the telecoms giant will no longer have access to Google's proprietary services - which include the Gmail and Google Maps apps - a source close to the matter told AFP.
But the Commerce Department on Monday issued a 90-day reprieve on the ban on the transfer of technology by allowing temporary licences.
"The US 90-day temporary licence does not have much impact on us, we are ready," Ren said.
Huawei has sought to ease customers' concerns over the Google announcement.
Ren said Huawei and Google are discussing how to respond to the ban, calling the US firm a "highly responsible company".
A company spokesman in Australia said the US actions "will not impact consumers" with a Huawei tablet or smartphone in the country, or those planning to buy a device in the future.
As for Huawei's access to key components, Ren said half of chips used in the company's equipment come from the United States and the other half it makes itself.
"We cannot be isolated from the world," Ren said.
"We can also make the same chips as the US chips, but it doesn't mean we won't buy them," he said.
He denied reports that German chipmaker Infineon has halted shipments to Huawei.
But analysts say the ban threatens the company's very survival as it heavily relies on US components.
"If the ban continues, Huawei will be damaged for sure, particularly in smartphones but also in the datacenter and networking markets," said Patrick Moorhead of Moor Insights & Strategy.
Ask Trump, not me
The Huawei confrontation has been building for years, as the company has raced to a huge advantage over rivals in next-generation 5G mobile technology.
US intelligence believes Huawei is backed by the Chinese military and that its equipment could provide Beijing's intelligence services with a backdoor into the communications networks of rival countries.
For that reason, Washington has pushed its closest allies to reject Huawei technology, a significant challenge given the few alternatives for 5G.
While Australia has also banned Huawei from its 5G plans, the US has struggled to sway some countries, with Britain having reportedly approved a limited role for the Chinese company to help build a 5G network in the country.
Canada has been dragged into the battle. Its arrest of Ren's daughter, Huawei chief financial officer Meng Wanzhou, in December on a US extradition bid linked to Iran sanctions violations was followed by the arrest in China of two Canadians, including a former diplomat.
"We sacrificed ourselves and families because we have a goal. In order to stand on the world's summit, for this goal, there will be conflicts with the US sooner or later," Ren said.
The battle over Huawei has added to tensions in a trade war that has escalated between the world's top two economies, with both sides exchanging steep increases in tariffs as negotiations have faltered.
China's envoy to the European Union, Zhang Ming, called the move against Huawei "wrong behaviour", adding "there will be a necessary response".
Asked how long Huawei may face difficult times, Ren said: "You may need to ask Trump about this question, not me."
