ByteDance Ltd.’s options for TikTok in the US are looking increasingly desolate, as the tech war between Washington and Beijing boils over. The mutual distrust and tit-for-tat animosity lays bare the new reality, where more firms will be pinched from both sides.

The move against the Santa Clara-based chipmaker follows other recent escalations; Beijing halted exports of certain minerals with tech applications to the US after Washington intensified chip curbs to China last week. China is also cutting off drone supplies to the US and Europe that have become a vital part of Ukraine’s defense.
