As the warm relationship between U.S. President Donald Trump and Brazil President Jair Bolsonaro comes to an end with the former’s electoral defeat in November 2020, the next two years (Bolsonaro is up for reelection in 2022) could prove to be strenuous for the bilateral relations of the two largest economies in the Western Hemisphere. President-elect Biden has signaled that combatting climate change will be a priority in his administration. Now, without the cover of a U.S. administration that denies climate change, Brazil could become further isolated in international environmental politics. All of this complicates the political realities for President Bolsonaro, whose political survival depends on maintaining his coalition of fanatical supporters, the agricultural sector, and former and current members of the military. Still, given U.S. concerns about Chinese influence in the region, the Biden-Bolsonaro relationship could prove to be low-key and practical.
