I'm trying to keep track of Brazil's reaction the Ukrainian war and its effects on the supply of fertilizer.

RT summarized Bolsonaro's stance on the conflict:

>In a press conference on Sunday, Brazilian President Jair Bolsonaro said the country would “not take sides” and would “continue being neutral” while helping with “whatever is possible.”
>Speaking about Ukrainian President Volodymyr Zelensky, who was one of Ukraine’s most popular comedians before his foray into politics, Bolsonaro said Ukrainians had “placed the hope of their nation in the hands of a comedian.”
>Unlike China and India, who abstained from voting for a UN Security Council resolution condemning Russia over Ukraine, Brazil ended up voting for the document. There have been reports in local media that Brazil sought to “soften” the wording of the resolution, but did not succeed.
Brazil hasn't joined economic sanctions and Russian state media seems to try to give him an opening for further realignment. Earlier on they echoed speculation that Putin deliberately gave him a warmer welcome than he did to Macron:

However, the Ministry of Agriculture expects food prices to rise and financial and logistic difficulties in proceeding with fertilizer imports. Western shipping companies are no longer an option. Some negotiations already began with Canada and some Arabs are also interested in being alternate suppliers. There are fertilizer stocks for three months and on the 4th a Russian cargo ship loaded with fertilizer departed towards Brazil. Russia has temporarily suspended fertilizer exports but businessmen believe that to be more of a suggestion. Workarounds will be sought around Western obstacles, but there's a lot of uncertainty.
