Brazil will be represented at the conference on Ukraine in Switzerland by a low-ranking official, writes O Globo (https://oglobo.globo.com/mundo/noticia/2024/06/04/lula-deve-enviar-diplomata-a-reuniao-na-suica-para-discutir-paz-entre-russia-e-ucrania.ghtml).

It was previously reported that the President of Brazil would not be attending the conference in Switzerland, and now it has been confirmed that neither the Minister of Foreign Affairs nor the International Affairs Advisor will be present.

"The idea is to send someone without decision-making authority, just for attendance," writes O Globo.

Brazil's ambassador to Switzerland, Cláudia Fonseca Buzzi, is expected to attend the meeting.
