The Saeima vote on Braže's nomination is expected on Thursday.
"I am glad that we have been able to find a person who is ready to undertake the leadership of the Foreign Ministry at a time where there is no time for preparation. Baiba Braže knows the Foreign Ministry, the foreign affairs service, and to a certain extent, politics," said Siliņa.
Braže is currently Ambassador-at-Large at the Ministry of Foreign Affairs. Previously, she was Latvia's Ambassador to the Netherlands and the United Kingdom, as well as NATO's Assistant Secretary General for Public Diplomacy.
She is currently not a New Unity party member but is planning to join the political force soon.
The invitation to join the Government was unexpected, said Braže: "It is undoubtedly a big step for me both professionally and personally."
She also outlined Latvia's priorities in the area of foreign affairs and security: "Strengthening our own security, strengthening our position as a member of NATO and strengthening the Alliance as a whole. It is our economic growth, including a strong, globally competitive European Union. (...) The third big point is the defense of our nationals and our citizens in the world."
Explaining the priorities, she stressed the need to prevent a resurgence of Russian military capabilities. "Here I think we can do more," added Braže.
The Saeima is expected to vote this Thursday on the confirmation of the next foreign minister. She is expected to hold talks with several factions in the Saeima before Thursday's plenary session.
