Belarus has no spare potash for Western buyers, President Alexander Lukashenko said before Donald Trump outlined plans to buy Belarusian fertiliser, Meduza reported on September 21.

Trump wrote on Truth Social that the United States was working on "a massive Deal" for Belarusian potash fertiliser, priced "substantially less than we are currently paying to Canada, very good news for our Farmers and Ranchers".

Lukashenko’s account raises a supply question for Washington’s proposed deal: lifting sanctions would not by itself free up volumes already committed to other buyers. The two leaders have not set out how those existing contracts would be reconciled with new US purchases.

"As far as I know... We've managed to shift our exports eastward. Our negotiations with the Americans are proof of that. A lot of people here are making a fuss about potash. Even if we wanted to supply other markets - Western markets - we simply don't have the volume. It's all under contract," Lukashenko said.

The United States imports nearly all the potash it uses, with Canada supplying close to 80% of those imports and Russia another 12%, according to the figures cited in the report.

Belarus ranks among the world's largest potash producers alongside Canada, Russia and China, but sanctions have restricted its access to Western markets since measures imposed over the crackdown on the 2020 protests and Minsk's part in Russia's war on Ukraine. Washington lifted its potash sanctions after Trump returned to office. The EU has not.

Washington has also been pressing Vilnius to reopen Klaipeda to Belarusian potash, the corridor that carried more than 90% of those exports before Lithuania halted transit in 2022. The US dropped its remaining sanctions on Belaruskali, Belarusian Potash Company and Agrorozkvit in March 2026 after Minsk released 250 prisoners under a deal brokered by special envoy John Coale, who argued that restoring the flow would ease fertiliser supply pressures on American farmers. EU restrictions still bind Lithuania.

Before the halt, the Lithuanian corridor connected landlocked Belarus to customers in China, India and Brazil. Lukashenko did not identify the buyers holding its current contracts in the remarks quoted by the report.
