New Japan Pro Wrestling is dissatisfied with TNA Wrestling's treatment of the IWGP Tag Team Championship. When TNA decided to change the champions from Team 3D to The British Invasion back in July, NJPW was unaware and didn't accept the change at first. The company recognized the change a month later.
We're told New Japan Pro Wrestling does not want The British Invasion to hold the IWGP Tag Team Championship because they are not over in Japan, unlike Team 3D and Kurt Angle. The reason why NJPW agreed to have their titles in TNA is for popularity.
Most fans in Japan still think Team 3D hold the IWGP Tag Team Championship and it might play a factor in the booking of Sunday's match at TNA Bound For Glory.
