The comments contradict Chinese media reports and market speculation about job cuts and a pull-back for China's internet sector amid weakening domestic demand and an prolonged trade dispute with the United States.
"This year we not only won't layoff employees, we will continue to utilise the resources on our platforms to boost consumption, bringing in more manufacturing and services orders," Zhang said in a Weibo post.
"When the economy is bad, the biggest advantage for online platforms is to create jobs."
This week reports circulated in Chinese media that e-commerce site and Alibaba rival JD.com Inc would lay off 10 percent of its senior executives. The company declined to comment directly on the cuts.
