Wow I never knew that. From wikipedia and I quote:
https://en.wikipedia.org/wiki/Collision_in_KoreaCollision in Korea, officially known as the Pyongyang International Sports and Culture Festival for Peace (平和のための平壌国際体育・文化祝典 Heiwa no tame no Pyon'yan kokusai taiiku bunka shukuten), was a professional wrestling pay-per-view (PPV) event jointly produced by New Japan Pro-Wrestling (NJPW) and World Championship Wrestling (WCW). It took place over a period of two days on April 28 and 29, 1995 at May Day Stadium in Pyongyang, North Korea. It aired in North America on August 4, 1995, when WCW broadcast a selection of matches from the show on pay-per-view.
The event was the first PPV from a North American wrestling promotion to be held in North Korea, and holds the current record for the largest combined attendance for a wrestling event, with a claimed crowd of 165,000 and 190,000 for the first and second day respectively. American wrestling journalist Dave Meltzer reported different attendance numbers of 150,000 and 165,000 respectively.
NJPW's Hidekazu Tanaka was the ring announcer for the show, while Masao Tayama and Tiger Hattori refereed the matches. Commentary for the WCW pay-per-view presentation of the event was provided by Eric Bischoff, Mike Tenay and Kazuo Ishikawa.
It is one of the few WCW pay-per-view events not made available for streaming on the WWE Network service.
