The People’s Republic of China objects to the sale of defensive weapons to the Republic of China.

China will sanction US firms that participate in arms sales to Taiwan [The Wall Street Journal‘s conflation of the island with the nation that sits on the island], after Washington approved sales of $2.2 billion in tanks, missiles and related military hardware, Beijing said.

The PRC’s Foreign Ministry has justified the threat with this:

the arms sales “harmed China’s sovereignty and national security”

Of course, it does no harm to the PRC’ sovereignty to sell weapons to a sovereign nation.  Of course it does no harm to the PRC’s national security to sell defensive weapons to a sovereign nation that’s so much smaller than the PRC.

All the sale does is increase a sovereign nation’s ability to defend itself against the aggression, the threats of invasion, which the PRC has so repeatedly leveled against that sovereign nation.  If the PRC has no such aggressive intent, it has nothing to fear from the sale.

The PRC’s moves would be nonsensical, did they not amount to such a cynical and naked and continued grab for power.
