 Two days later, the Taipei Prosecutor's Office declared Wang a wanted fugitive, and his ROC passport was revoked by the Ministry of Foreign Affairs (MOFA).MOFA also contacted the US Department of Justice (DOJ) requesting assistance in having Wang extradited back to Taiwan.However, this proved to be difficult as the ROC's diplomatic isolation meant that it had few standing extradition agreements with other states, though US authorities did have an information sharing system in place which was used to coordinate efforts between the two sides.
