Zhang's comments come two days after Alibaba announced its largest restructuring in the company's history, which will see it change into a holding company structure with six business units, each with their own boards and CEOs.
The business units will have their own CEOs and boards, though Alibaba will retain seats on those boards in the short-term, Zhang added.
Alibaba began laying the groundwork for the restructuring a few years ago, Zhang told investors during a conference call, adding the business units could pursue public listings on their own in the future.
After these units go public, Alibaba "will continue to evaluate the strategic importance of these companies" and "will decide whether or not to continue to retain control," Alibaba CFO Toby Xu said on the call.
Alibaba, however, will decide whether the group wants to keep strategic control of each unit after they go public, Xu said.
