Mariano Sabino Lopes (born 12 April 1975), also known by his nom de guerre Assanami, is an East Timorese politician and a member of the Democratic Party (PD).

There, he joined the National Resistance of East Timorese Students (Portuguese: Resistência Nacional dos Estudantes de Timor-Leste (RENETIL)).

Amongst other things, he formulated plans to infiltrate the Ikatan Mahasiswa dan Pelajar Timor Timur (IMPETTU), the Indonesian-East Timorese student association.

At that time, he was Deputy Secretary General of RENETIL and head of Ikatan Mahasiswa dan Pelajar Timor Timur (IMPETTU), the East Timorese student association.

In some cases, according to an audit to the Ministry of Agriculture and Fisheries, contracts for the supply of goods and services were made with companies close to Sabino, without complying with the required procedures.
