ROH is no longer allowing any contracted talent, whether they have exclusive or non-exclusive deals, to work for AAA. The reason for this is because ROH, NJPW, and CMLL are trying to work out a three-way relationship.
NJPW doesn’t want ROH to work with their competitor, AAA, and because of that, ROH is attempting to open up business with CMLL.
