At an AIBA congress in Lausanne in Switzerland last month, 95 percent of delegates voted to allow professional boxers for the first time ever to enter the competition.
The decision was met with widespread derision in the boxing world, with many making their views clear even before the change was made.
AIBA president Wu Ching-Kuo said the organisation had no plans to take over the sport and allowing professionals to compete in Olympic boxing was a great step forward for it.
"We never said we want to take over boxing. We just want to open the door because no one can stop athletes from going to the Olympics, that is a fundamental concept," Wu said.

In May legendary boxing promoter Bob Arum told AFP the plan to introduce professional boxers was "total madness" and would result in "serious injuries".
But Wu rejected the charges saying that "only the best AIBA boxers" would be facing professional fighters.
Speaking about the new relationship with Alibaba, Wu predicted a bright future for boxing in China, which he described as a "noble sport" that could "prepare youth for the challenges which they face in society".
