Which country was NOT included in the Treaty of Paris aftermath of the Spanish-American War?

The Treaty of Paris, signed in 1898, formally ended the Spanish-American War and resulted in the cession of significant territories from Spain to the United States. Key provisions of the treaty included the recognition of Cuban independence, the cession of Guam and Puerto Rico to the United States, and the sale of the Philippines to the U.S. for $20 million.

Mexico, however, was not involved in the Treaty of Paris as it was not a party to the conflict between Spain and the United States. The country remained neutral during the war and was not impacted by the outcomes outlined in the treaty. The terms of the treaty focused solely on the fate of Spanish territories, which makes Mexico the country excluded from the agreement. Thus, the correct answer identifies Mexico as not being affected by the Treaty of Paris following the Spanish-American War.
