How have trade agreements changed over time to address the challenges of modern global trade?

Because global trade has become more common, and practically every single country engages in it, trade agreements have become larger, more complex, but in the end, more supportive of global trade.

Explanation:

For example, in the 1990s, NAFTA was a revolutionary trade agreement, because it was signed by three large economies: the United States, Canada, and Mexico.

However, recently, most of Asia signed a new trade agreement led by China, that includes many more countries like Japan, South Korea, Vietnam, and Indonesia.
