There was an agreement that was signed between Kwaku Dua I and King William I, that Kwasi Boakye was to return with his cousin, Kwame Poku after they are done with their studies.

Kwame Poku did return to the Dutch Gold Coast as planned, Boakye stayed in the Netherlands.

[4][5] In July 1847, Boakye had lectures at the Freiberg Mining Academy (Technische Universitat Bergakademie) in Germany.

Boakye was sent to the Dutch East Indies in 1850, where he found himself discriminated against by his superior, Cornelius de Groot van Embden, for which he received a financial compensation in 1857.

[1] Dutch writer Arthur Japin has written a historical fiction novel based on the Boakye brothers' lives, The Two Hearts of Kwasi Boachi, released in 1997.
