Which of the following is a major component of the role of the World Trade Organization (WTO)?

The World Trade Organization (WTO) primarily focuses on facilitating and regulating international trade between nations. A key component of its role is the resolution of trade disputes. This involves providing a structured process through which member countries can address disagreements related to trade agreements, tariffs, and other trade barriers. By offering a neutral forum for dispute resolution, the WTO helps ensure that international trade operates smoothly and fairly, supporting the overall goal of promoting free trade and economic cooperation among nations.

The other options do not align with the primary functions of the WTO. While labor standards, environmental regulations, and defense policies are important issues in global governance, they fall outside the specific mandate of the WTO, which is dedicated to trade-related matters. The WTO does not regulate labor standards directly, monitor environmental regulations, or establish defense policies, which reinforces the importance of recognizing its unique role in facilitating trade relations worldwide.
