Our comprehensive assistance spans several trade capacity areas, including non-tariff trade barriers, services trade, trade facilitation, e-commerce, digital trade, trade facilitation agreement implementation and compliance, regional integration, and customs modernization. We build the capacity of customs and enforcement officials, improve the legal and regulatory environment, and design and integrate trade information portals, single windows for trade, and other technology to expedite clearance and enforcement.
