Lets not sell this achievement short. There were almost certainly intense back channel efforts and negotiations to pull this diplomatic coup off. It’s difficult to put into words exactly how much work it is to get everyone on the same page before you pull them together for a meeting to officiate new political realities. I’ve been involved with these kinds of things on an infinitesimally smaller scale stitching together local communist groups previously cleaved off from each other by sectarian divisions. Its taken me a long time just to get a hearing with some of them, groups with virtually no serious political differences at all, let alone two state authorities that have been divided by deep seated religious and military conflict.
