In the article, experts looked at regional trade deals to see if they could help make global trade rules more common and stronger. They studied how these deals go beyond what the World Trade Organization (WTO) asks for. They found that more regions are adding similar extra rules over time. This suggests countries might be more open to agreeing on stronger rules. The study picked out some qualities that could make these extra rules more likely to be used globally, either through other trade deals or by the WTO itself. By analyzing how well different regions are working together, how fair the rules are, how easily they can be enforced, and how they affect economies, researchers aim to encourage better trade practices worldwide.
