Mr He’s findings are set to be unveiled at a Hong Kong conference on gene editing on Tuesday.
The event, The Second International Summit on Human Genome Editing, organised by the Royal Society, takes place on November 27-29.
The purpose of the international summit is to help determine whether humans should begin to genetically modify themselves and if so how.
Mr He’s alleged breakthrough may have preempted the meeting's impetus, with the elite biologist recruited back to China from the US as part of its “Thousand Talents Plan”.
In a pre-recorded message ahead of the event, David Baltimore, a biologist and chair of the international summit's proceedings, said: “We have never done anything that will change the genes of the human race, and we have never done anything that will have effects that will go on through the generations.”
