• A slew of high-profile leaders have been targeted by China's tightening regulations.
• In recent months several executives have been barred from leaving the country through exit bans.

China has grown noticeably colder toward businesses — and their top leaders — in recent years.

Under Xi Jinping's leadership, authorities have cracked down on private sector companies, raided the offices of major firms, slowed the approval of deals, and targeted a slew of high-profile executives. Many of these leaders have been subject to investigation, barred from leaving the country, placed under surveillance, or have even gone missing.

China's tightening regulations have also triggered concerns overseas. In June, the US State Department issued an updated travel advisory to mainland China alerting potential travelers to the "arbitrary enforcement of local laws, including in relation to exit bans, and the risk of wrongful detentions."

Here's a closer look at the growing list of execs that have been targeted by Chinese authorities.
