ByteDance founder Zhang Yiming has stepped down as chairperson of TikTok after saying in May he would no longer be CEO, a person with direct knowledge of the matter told Reuters, marking the latest shake up at the tech giant.

New CEO Liang Rubo has taken over as chair of the company's five-person board, which also includes General Atlantic, Sequoia Capital, Coatue Management and Susquehanna International Group, the person said, adding that the decision was made this year.

It was not immediately clear when Zhang relinquished the chairperson title and whether there have been any changes to his more than 50% voting rights at the company.

ByteDance said in May that Zhang would move to a "key strategy" position at the end of the year. The person said that plan was unchanged. ByteDance did not immediately respond to a request for comment.

Zhang 's surprise announcement in May saw his college roommate and co-founder Liang take the lead in navigating the company through a rising wave of new regulations targeting Big Tech.

The move comes after the company on Tuesday announced a major organizational reshuffle at ByteDance to create six business units.

It also said that TikTok CEO Shou Zi Chew would step down as its parent ByteDance's chief financial officer (CFO) to focus on running the short video platform full time.

A number of founders at some of China's most well-known tech companies have in recent months given up overseeing daily operations amid a wide-ranging clampdown by Chinese regulators on large swathes of the economy.

Last week, short-video apps owner Kuaishou said its co-founder, Su Hua, had stepped down as CEO.

E-commerce company Pinduoduo founder Huang Zheng stepped down as chairperson this year, having earlier relinquished his CEO title.

Alibaba founder Jack Ma retired as chairperson of the e-commerce giant in 2019.
