In 1932, it was decided to amalgamate with the Narcissus Tennis Club of La Penitence which had been started in 1909 comprising Chinese lawn tennis players.

In May 1945, a larger Pavilion was built and all indoor activities were now transferred from the Chinese Association to the Chinese Sports Club at Thomas Lands.
In 1963, it was decided that membership of the club should no longer be restricted to Chinese but should be opened to all races. The Club's name was also changed to Cosmos Sports Club.
By 1984, most of the Chinese members of the Club had emigrated and it was decided to merge Cosmos Sports Club with the Guyana Motor Racing and Sports Club and to rename the club the Guyana Motor Racing and Sports Club.
