China extended congratulations to Brazil's new president Luiz Inacio Lula da Silva on his re-election, despite Bolsonaro's refusal to accept defeat. The Foreign Ministry stated that China is "willing to work with Brazil to continue advancing the building of a China-Brazil community with a shared future." A range of international political figures and institutions also extended their congratulations, including Mexico, Cuba, Argentina, India, France, and the European Union, emphasizing the importance of democracy, multilateralism, and partnership. Lula won with 51.8 percent of the vote compared to 48.2 percent for Bolsonaro. Bolsonaro, however, announced his intention to annul the election due to technical issues surrounding voting delays and the extension of polling hours.

Bolsonaro's announcement to annul the election was based on the extended voting hours due to legal disputes and weather conditions. This move sets the stage for further confrontation between the parties. Earlier, the Superior Electoral Court confirmed Lula as the winner, a result that is now being challenged. The incident also reflects broader tensions within Brazilian politics, particularly surrounding the handling of the election process.
