How China responded to the U.S. shooting down the balloon:
China’s Ministry of Foreign Affairs issued a statement saying, “China will resolutely uphold the relevant company’s legitimate rights and interests, and at the same time reserving the right to take further actions in response,” per AP News.
With some standard diplomatic chatter that says nothing.
We shot down one of theirs. They will certainly shoot down or blind the next one of ours. Just like they probably did to previous ones of ours if they were able to do so. Unmanned systems are cheap and expendable.
The game goes on.
