In what way was Puerto Rico treated differently from Cuba in the peace treaty?

In the peace treaty following the Spanish-American War, Puerto Rico was treated differently from Cuba primarily in terms of sovereignty. While Cuba was granted independence, albeit under U.S. oversight through the Platt Amendment, Puerto Rico was ceded to the United States as a territory, meaning it remained under U.S. control without the promise of independence. This distinction highlighted the U.S. approach to governance and territorial expansion, treating Puerto Rico as a colony while allowing Cuba a degree of self-governance.
