To my knowledge The recognition of the date of Indonesian independence by the Dutch was an event in which the Dutch finally recognized that Indonesia's independence was August 17, 1945 in accordance with the proclamation of Indonesian independence, not December 27, 1949 when the soevereiniteitsoverdracht was signed at Dam Palace, Amsterdam.
This recognition was made on August 16, 2005, the day before the 60th anniversary of the proclamation of Indonesian independence, by Dutch Foreign Minister Bernard Rudolf Bot in his official speech at the Department of Foreign Affairs. On that occasion, the Government of Indonesia was represented by Foreign Minister Hassan Wirajuda. The following day, Bot also attended the State Ceremony Commemoration of the 60th Anniversary of Indonesian Independence at the State Palace, Jakarta. This Bot step breaks the taboo and is the first in history.
