Recently the Russian Ministry of Finance stated it expects Venezuela to provide payments on time.
Given the U.S. has imposed sanctions against Venezuela, would the economic influence on Venezuela give Russia legitimate reason to include the U.S. or other nations in actions to recover the loan?
To clarify further, I am looking for any existing precedents on international law or Russian history (from the beginning of the Russian Empire, 18th century, roughly when the U.S. started just to pick a date) that would lend credence to Russia legitimately pursuing the U.S. for impairing Venezuela's capacity to repay the loan. Looking for historical evidence or cited context on previous examples that may be relatable to the current situation.
Are there actions Russia can take on Venezuela that the U.S. would be obliged to honor?
A hypothetical example: The US would be forced to pay the loan for Venezuela by breach of a treaty. Or, alternatively, the US would be forced to allow Russia to confiscate Venezuelan assets.
I am seeking potential actions based on evidence. Also, this is not speculating on motives or willingness to comply. Evidence being an treaty, declarations, or action done in a analogous situation.
The heart of what I am seeking is what happens to Venezuela if it doesn't pay Russia what it owes Russia?
Edit: Added some context. This is not seeking speculative or opinionated answers. The primary part of the question is focused on Venezuela. Anything related to the U.S. is ancillary.
