The key economic agreement signed to promote trade among several nations in the early 21st century was the Trans-Pacific Partnership (TPP). This agreement aimed to enhance trade and investment relationships between Asia-Pacific countries, focusing on reducing tariffs, promoting fair labor standards, and environmental protection. Although initially signed in 2016, the TPP faced significant political opposition, particularly from the U.S., which ultimately withdrew in 2017. Despite this setback, the TPP set a framework for potential future trade agreements and highlighted the complexities of globalization, balancing economic growth with ethical considerations in trade practices.
