What is the primary function of the WTO?

The World Trade Organization (WTO) was established in 1995 to replace GATT (General Agreement on Tariffs and Trade).
Its primary function is to facilitate smooth, fair, and free international trade among member countries.
WTO works to:
Reduce trade barriers like tariffs and quotas.
Ensure fair competition and transparency in global trade.
Provide a platform for trade negotiations.
Settle disputes between member nations.
It does not promote only domestic trade, regulate tourism, or finance countries—that is the role of other organizations like IMF or World Bank.
