25 000 Dobras Treaty with European Union

São Tomé e Príncipe signed a cooperation agreement with the European Community in 1989, part of the broader Lomé Convention framework that tied ACP nations to preferential trade arrangements with Europe. This coin was issued four years later, presumably to mark ongoing diplomatic engagement rather than any single treaty event — the island state had limited leverage in those negotiations and was largely a beneficiary of aid provisions rather than an active party shaping terms.
