While the US and Huawei kept their conflict muted during Mobile World Congress last week, they have wasted little time in picking up where they left off after that brief hiatus.

Having said that there was widespread talk on the show floor last week that there were many representatives of the US government and other public institutions at the event, apparently canvassing for support.

Anyway, the BBC reports that last Friday Huawei’s CFO, Meng Wanzhou, filed a civil suit against Canada for breaching her civil rights when it arrested her late last year.

The move coincided with the official commencement of her extradition process to the US, which wants to try her for a bunch of alleged crimes.

Her case seems to rest on some perceived irregularities in the process by which she was arrested, but is probably part of a broader coordinated legal counter-attack by Huawei.

Meanwhile Huawei is also preparing to sue the US government, according to multiple reports, the first of which seems to have come from the New York Times.
