I am a foreign trade salesman of the company, and I was cheated on a single trade (international mail fraud). The boss doesn't know the truth and won't listen to me. According to foreigners.

Hello, first of all, answer your question. According to the information you provided, your boss does not constitute the crime of false accusation and frame-up. The boss's ignorance stems from misunderstanding, rather than fabricating facts to frame you in public security organs in order to get you criminally investigated. You can provide your own excuses and relevant evidence to the public security organs to clarify the facts.

Crime of false accusation and frame-up: a serious act of fabricating facts and falsely accusing and framing others with the intention of making them subject to criminal investigation.

If you want to accuse him of a crime, you must produce directional evidence. For example, he fabricated facts (serious enough to be subject to criminal punishment), and subjectively and maliciously proved that he intended to subject you to criminal investigation, and so on.

I hope it helps you.
