<h1>Senior envoy urges collective defence of WTO trade rules, condemns 50% tariffs, calls for reciprocal market access and non-discrimination</h1> A senior envoy from one country publicly opposed a third country's imposition of up to 50% tariffs on another country, characterizing silence or compromise as acquiescence and urging collective defence of the WTO-based multilateral trading system; the envoy also criticized the use of tariffs as a bargaining chip and noted additional duties tied to energy purchases. The statement addressed trade retaliation, called for reciprocal market access and non-discriminatory treatment for investors, referenced a recent 10-point diplomatic consensus on a bilateral border dispute to be advanced in parallel with cooperation, and said leaders' summit preparations are underway.
