Notable economic partnerships?

If you mean major partnerships between countries or regions, a few stand out for their reach and influence:

• European Union single market: Enables the free movement of goods, services, capital, and people among participating EU countries.
• US-Mexico-Canada Agreement (USMCA): Sets trade rules for North America and replaced NAFTA in 2020.
• ASEAN Economic Community: Supports economic integration among Southeast Asian nations, including closer trade and investment ties.
• African Continental Free Trade Area (AfCFTA): Seeks to expand trade among African countries by reducing barriers and creating a shared market.
• Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP): A trade pact connecting economies across the Asia-Pacific and the Americas.

These differ in how deeply they integrate their members: some focus mainly on trade rules, while others also encourage cross-border investment or broader economic coordination. If you had a particular region or time period in mind, the most relevant examples may be different.
