A short-stay visa waiver agreement between Tonga and the EU was signed this week allowing visa-free travel for EU citizens when travelling to Tonga.
Tongans travelling to the EU (Schengen area) will also not need visas.
The Agreement applies on a provisional basis as of 21 November 2015.
An EU statement said the agreement would encourage people-to-people contacts, boost tourism, and invigorate business.
