 In 1993 the journalist and former colonial soldier cordially toured together with Princen the battlefields where they had fought on opposing sides, and made a documentary.However, Vaders' attempt to secure Princen a visa to visit the Netherlands failed, the government claiming that war veterans had threatened to kill him if he tried to enter the Netherlands.In 1994, then Dutch Foreign Minister Hans van Mierlo finally overruled the officials at the Jakarta Embassy and personally authorised to issue Princen a visa "on humanitarian grounds" – on condition (which was kept) that he maintain "a low profile" during his visit to the Netherlands and devote it mainly to meeting family members who he had not seen for many decades.
