agreements are of no value

Actually, it was the U.S. gubmint that upheld the agreement. The full article states:

After a new president of Panama took over in July 2014, however, its [the Panamanian] government reneged on the agreements.

This week attorneys with the U.S. Customs and Border Patrol upheld Porter's claims of ownership and ordered the treasure released to him in Fort Pierce.
