Jack Ma, co-founder of China's most valuable company, was officially confirmed as a member of the Communist Party in a state-backed newspaper recognizing business leaders for their contributions to the country's development.

Ma, co-founder and chairman of e-commerce giant Alibaba Group Holding Ltd., is one of 100 people the Communist Party of China's Central Committee will honor as part of a celebration marking 40 years since the country's economic reform and opening up. The honorees also include Tencent Holdings Ltd. Chief Executive Officer Pony Ma, Baidu Inc. CEO Robin Li, basketball star Yao Ming and volleyball coach Lang Ping.

The lines between business and politics have become increasingly hazy in China as President Xi Jinping has led a campaign to ensure the Communist Party plays a leading role across all aspects of society. That has at time created tensions when the interests of private business people and the state have conflicted.
