There will be cooperations with other gangs when the opportunity for making money requires it. Otherwise there is little interaction between JSB and other gangz for fear that other gangz may know their secrets. Smuggling to Canada, HK, S.E.A., Taiwan, or China is constant, though their is not a direct affiliation with any gang in Asia, everybody cooperates because making money is the ultimate goal. There might be an affiliate living in the U.S. who knows a certain HK faction and is also in good terms with JSB, a deal would be worked out between the two gangz and their they would have their affiliation, after the deal, everybody collects their money and goes their own wayz. JSB have worked with triadz such as 14K, BCB, and many others which do not go by names anymore.
Names are no longer significant, and are actually easy identifiers for law enforcement.
A person might have been indoctrinated as a BCB but he might work with all 14k or SunYeeOn, nobody will question his loyalty, because everyone is loyal to money. When they return to the gang'z main city, they use their former connectionz within their triad to make even more money, and if the people he grouped with aren't with any other triad, they are indoctrinated as well, to make the gang bigger. All Triadz and Chinese Law Enforcement Officers pay homage to Guan Yu ,the god of war, for he exemplifies loyalty and courage, important to both criminal groupz, and police.
