The US Commerce Department has refused to renew an export licence at a Huawei subsidy in Silicon Valley, meaning China cannot access new developments at the site.

According to the Wall Street Journal, Huawei R&D outfit Futurewei was informed over the summer that the US Department of Commerce would not be renewing the license meaning some of the technologies developed at the site, but not all, could not be exported back to China. It’s a new strategy in the conflict between the US and China, but it could prove to be an effective one.

Silicon Valley is not the hotspot of the technology world because of the favourable climate or the presence of helpful regulations, it has one of the most talented workforces around the world. There are of course challengers to this claim emerging, India or Eastern European for example, but companies flock to Silicon Valley to open up R&D offices to tap into this resource. Such a ban from the US Commerce Department means Huawei is going to miss out on some of these smarts.

The block will prove problematic to overcome as there does not appear to be any logical way to combat the move. The rationale behind the blockage is quite simple; national security. Seeing as Huawei is currently being trialled and punished without the burden of evidence, there seems to be little the vendor can do to combat such passive aggressive moves by the US.

This is of course just another stage is the incrementally escalating conflict between the US and China. The tension between the pair does seem to have escalated over the last few days following a minor hiatus at Christmas. Rumours are circling the Oval Office concerning an all-out ban on Huawei and ZTE technology in the US, while suspicions will only increase following the arrest of a Huawei employee in Poland on the grounds of espionage.

With all the drama before Christmas and the hullaballoo kicking off again now, perhaps we should expect some sort of retaliation from Beijing. The Chinese governments has not been anywhere near as confrontation as the US, though there might be a breaking point somewhere in the future.
