Huawei was on the table for discussion during President Donald Trump’s visit to the United Kingdom this week, although there were mixed signals on whether the U.K. government would bow to U.S. pressure and exclude China-based equipment manufacturers from future 5G networks.

Earlier on Tuesday, Reuters reported that Prime Minister Theresa May planned to tell Trump that the U.K. is reviewing “the right policy” on Huawei and its involvement in 5G. May’s spokeswoman reiterated previous remarks that “any decision that we take will be supported by a hard-headed, technically informed assessment of the risk.”

In early May, leaked documents indicated that the U.K.’s National Security Council (NSC) had agreed to allow Huawei to contribute non-core parts of 5G mobile infrastructure such as the antennas. The then U.K. Defense Secretary Gavin Williamson was fired after May received “compelling” evidence of his involvement in the leak, although Williamson has denied any involvement.

However, a report in The Guardian this week said “cryptic remarks” from Trump now suggested that May could water down her plan to let Huawei have limited involvement in the 5G network. According to the report, Trump said there should be “no problem” with intelligence sharing between the U.S. and the U.K. based on his conversations with May. The U.S. has previously signaled that the use of Huawei equipment could harm intelligence sharing between the two countries.

A second Reuters report also cited comments from Trump that said the two countries would work out any differences over Huawei, and dismissed any suggestion that disagreement could threaten intelligence sharing.

Huawei was also targeted by a presidential executive order banning it from purchasing U.S.-made products. And a top executive was accused of participating in a conspiracy to steal intellectual property from California-based CNEX Labs, which makes solid-state storage.

It’s unclear whether more will be said about Huawei during Trump’s visit, and the degree to which the treatment of China-based vendors will impact Anglo-U.S. relations remains to be seen. One thing is for sure: the situation is becoming increasingly complex for the embattled vendor, which is also facing heightened competitive aggression from competitors over 5G. Nokia, for instance, just trumpeted that it has now won 42 commercial 5G deals, of which 22 are with named customers.
