<h1>EU-US trade deal trust questioned after threatened Greenland tariffs; diplomatic good faith and trade stability at risk</h1> An EU official criticised a US executive's public threat to impose tariffs over Greenland as breaching an earlier bilateral trade agreement and undermining international good faith; this reasoning treats the prior political agreement as creating expectations of non-escalation, with the operative effect of framing the tariff threat as damaging to trade stability and diplomatic trust. The official characterised such tariff measures as inappropriate between long-standing allies, thereby signalling potential diplomatic and commercial consequences and reinforcing reliance on negotiated trade commitments as a basis for predictable relations.
