what does exactly this word mean ? cross-debt ? and how to use it ?

I believe the “cross-” applies to the whole phrase “debt payment guarantees” rather than just “debt”.

My understanding is that a “debt payment guarantees” is issued among the companies in the same chaebol (a group of companies controlled by the same family and thus specially connected), in a multi-way fashion.
So “cross-” just means this concept of multi-way connections, which is a collection of “mutual” issuances among the many members.

“cross licensing” may be a similar concept more commonly heard, although it seems more often used for agreement between two companies.

Indeed, there is also the adjective “cross-guaranteed”.

cross-debt payment guarantees = cross guarantees for debt payment

Yes. That makes it lucid and clear.

Thanks you.
