Timor Leste signed a treaty with Australia this year resolving a long-standing boundary dispute.
Vanuatu's Prime Minister Charlot Salwai and Timor's chief negotiator on maritime boundaries, Xanana Gusmao, met this week in Port Vila.
A government statement said Mr Salwai wants Vanuatu to learn from Mr Gusmao, who mentioned Vanuatu's support for his country's fight for independence.
Mr Gusmao suggested Vanuatu raise the issue of maritime boundaries at the United Nations.
Vanuatu held talks this year with France over the Matthew and Hunter islands.
