Previously, between August 2012 and February 2015, he was Secretary of State for the Combatants for National Liberation Affairs, and in 2017–2018 he was a Member of the National Parliament.
Political career
2007–2018: Candidate, Secretary of State and parliamentarian
In the 2012 parliamentary election, Costa was in 13th place on the list and narrowly missed out on a Parliamentary seat, despite the waivers of some of those who had been higher in the list.[2] In any case, he would have had to forego any such seat, as on 8 August 2012 he was sworn in as Secretary of State for the Combatants for National Liberation Affairs in the V Constitutional Government, headed by Xanana Gusmão.[3][4] On 16 February 2015, his tenure in that position came to an end due to a government reshuffle.[5]
In the 2017 parliamentary election, Costa was placed in 8th position on the PD list. Although the PD won only seven seats, one of its candidates, António da Conceição renounced his seat, and Costa succeeded him. On 6 September 2017, the second day of the ensuing Parliamentary session, Costa was elected a First Deputy Speaker of the Parliament.[6][7] During that session, he was also a member of the Committee for Foreign Affairs, Defence and National Security (Committee B).[8] In the 2018 parliamentary election, Costa was in list position 7, and again missed direct entry into Parliament, as the PD won only 5 seats.[9]
2020–2023: Minister
On 29 May 2020, as part of a restructuring of the VIII Constitutional Government, Costa was sworn in as Minister for the Affairs of National Liberation Combatants in that government.[10][11][12]
Soon after taking that office, Costa announced that his ministry would be distributing a survey in communities across the country, to collect data on those who had died during East Timor's war of liberation. The government had decided to collect that data to enable the names of the deceased to be included in monuments that would be built throughout the nation.[13][14]
In July 2021, Costa publicly lamented the inadequate state of East Timor's public hospitals [translation]:
"Many seriously ill people including veterans have to be referred to overseas hospitals to have their health checked because in Timor Leste there is no international standard hospital including Guido Valadares National Hospital (HNGV)".[15]
He went on to observe that the government through the Ministry of Health was therefore forced to spend a lot of money to pay for aeroplanes, hospital fees and accommodation costs for the safety of its people.[15]
In September 2022, while giving a speech at the inauguration of a monument in the village of Leolima, Hato-Udo, Ainaro municipality, Costa commented as follows about young persons who participate in East Timorese ritual arts groups [de] [translation]:
"I believe that all young people can follow the various martial arts but at the same time you should also take part in unifying activity to create a memory for us in the future."[16]
In 2023, Costa was unsuccessful in proposing to the Council of Ministers that US$500,000.00 be allocated for spending on schooling and healthcare for children of veterans. However, during a speech delivered in Baucau municipality in February 2023, he pledged to continue to press the issue.[17]
Later that month, Costa called on all veterans, youth, and students to participate in Veterans Day on 3 March 2023, to honour and respect veterans who had put their lives at risk fighting for East Timorese independence. He also asserted that [translation], "We need to inculcate patriotism and nationalism in our children in order to promote peace and stability in the country."[18]
