Which major international organization plays a role against illicit trade?1 pointWorld meteorological organizationOSCEOECD

The major international organization that plays a significant role in combating illicit trade is the OECD (Organisation for Economic Co-operation and Development).

The OECD focuses on policy recommendations and collaborative efforts among member countries to effectively address issues related to international trade, including the challenges posed by illicit trade such as smuggling and counterfeiting. In particular, the OECD conducts research, provides data, and develops best practices to enhance transparency and integrity in trade policies globally.

In contrast, the World Meteorological Organization focuses primarily on weather, climate, and water resources, while the OSCE (Organization for Security and Co-operation in Europe) deals more with security and peace in Europe rather than specifically addressing illicit trade.

Thus, the correct answer to the question is OECD.
