In addition to the above answer, the World Trade Organization(WTO) helps developing nations adhere to domestic and international standards by deploying measures aimed at removing TBT(Technical Barriers to Trade), thereby impacting the countries' international exports and trade balance.
The WTO helps developing countries by offering a rules-based multilateral forum that reduces discriminatory trade barriers, provides dispute-settlement mechanisms, grants technical assistance and capacity-building, allows special and differential treatment provisions, and creates negotiating space for tariff bindings and market access — but actual gains depend on negotiation capacity, implementation resources, and complementary domestic reforms.
