[5] Nevertheless, it was believed that some other leading figures in the ruling party were skeptical about Vicente, given his relative inexperience in politics, and could be trying to resist the President's efforts to position him for the succession.

[14] In August 2014, Vicente participated in the United States–Africa Leaders Summit, an initiative of the American president, Barack Obama, held in Washington DC under the theme "Investing in the future of Africa.

He defended a reform in the UN Security Council, which should “be more in line with the international context and reflect an equal geographical representation through the increase in the number of permanent members”, namely by including an African country.

He approached issues such as the resurgence of armed conflicts, the religious fundamentalism in some African countries, the importance of disarmament and the combating of drug and human trafficking and transnational organized crime.

[17] In 2020, Vicente was described as mastermind of a triumvirate alongside Leopoldino Fragoso do Nascimento and Manuel Hélder Vieira Dias Junior, who built a secret banking network to transfer millions of dollars out of Angola.
