One of the clauses of the Budapest Memorandum is (page 20):
The Russian Federation, the United Kingdom of Great Britain and Northern Ireland, and the United States of America reaffirm their commitment to the Republic of Belarus, in accordance with the Principles of the CSCE Final Act, to refrain from economic coercion designed to subordinate to their own interest the exercise by the Republic of Belarus of the rights inherent in its sovereignty and thus to secure advantages of any kind.
Or, more plainly,
[Russia, the UK and the US agree to] Refrain from using economic pressure on Belarus ... to influence their politics.
It seems arguable that by imposing sanctions on Belarus (example) the US and UK are now also in breach of the Budapest Memorandum.
Has any US or UK leader explained their sanctions on Belarus in the context of the Budapest Memorandum, in particular if they view themselves as in breach? If they do not view themselves as in breach, why not?
It looks like the US already imposed sanctions on Belarus in 2013, and provided this as an explanation:
Repeated assertions by the government of Belarus that U.S. sanctions violate the 1994 Budapest Memorandum on Security Assurances are unfounded. Although the Memorandum is not legally binding, we take these political commitments seriously and do not believe any U.S. sanctions, whether imposed because of human rights or non-proliferation concerns, are inconsistent with our commitments to Belarus under the Memorandum or undermine them. Rather, sanctions are aimed at securing the human rights of Belarusians and combating the proliferation of weapons of mass destruction and other illicit activities, not at gaining any advantage for the United States.
I am looking for a more recent statement on the 2022 sanctions.
