<h1>Country A investigates whether Country B's proposed tariffs of up to 50% on 1,400 products are protectionist</h1> Country A has opened an investigation into whether import tariffs proposed by Country B-taxes up to 50% on more than 1,400 Asian-origin products to shield domestic industry-constitute a trade and investment barrier harming affected countries' interests. Country A said such measures are protectionist amid rival tariffs by a third country and announced a separate anti-dumping probe into pecan imports from Country B and the third country. The probe may lead to consultations, multilateral settlement or other measures under relevant investigation rules, though concrete action against Country B is not assured.
