Indonesia has become a full member of BRICS, a bloc of emerging economies that is increasingly seen as a counterweight to the West.
Brazil's foreign ministry said Southeast Asia's most populous country "shares with other members the will to reform the institutions of global governance and contribute positively to cooperation within the Global South."
Brazil, which holds the group's rotating presidency in 2025, said Indonesia's bid to join the bloc was approved during the 2023 summit in Johannesburg.
Indonesia in turn welcomed the announcement.
"This achievement demonstrates Indonesia's increasingly active role in global affairs and its commitment to strengthening multilateral cooperation to create a global architecture that is more inclusive and equitable," the foreign ministry said in a statement.
BRICS was established in 2009 by founding members Brazil, Russia, India and China. They were joined by South Africa the following year.
Last year, the bloc was expanded again, with Iran, Egypt, Ethiopia and the United Arab Emirates becoming full members.
Indonesia sees its BRICS membership as "a strategic step to improve cooperation and interaction with other developing countries based on the principle of equality, mutual respect and sustainable development," Jakarta said.
The position paper also expressed Indonesia's "gratitude to Russia", which holds the BRICS presidency in 2024, "for its support and leadership in facilitating Indonesia's accession", as well as to Brazil. | BGNES
