Ireland has enough domestic issues. It should not care about China.
Ireland’s already ruled from outside as it is. The guy who is currently serving as deputy PM said two years ago that “we have no interest in a backward-looking idea of sovereignty”, basically dumping his human waste on those who died fighting for independence.
Most of this “diplomatic” gesture is about selling beef to Red China after the last BSE scare (also to meet “climate goals” by reducing domestic bovine flatulence), and selling junky BYD electric cars in Ireland.
