That's not exactly true. While China doesn't detain US citizens (yet!) it detains several Canadian citizens presumable because the Huawei's CFO has been arrested in Canada by a US request. See https://time.com/5626289/china-canada-arrest-yantai/

Which makes things even worse - you may become a hostage due to US/China conflicts even if you happened to be a citizen of a US ally.
