One arrested, two missing amid probe of Chinese factory that makes Ivanka Trump shoes

What we know:

• Li Zhao and Hua Haifeng were not allowed to leave China in April and May.
• Hua told the executive director of the watchdog group the police asked him to stop investigating the factory.
• The director says he then lost contact with the two missing men over the weekend and said they haven't returned dozens of missed calls.
• A friend of one of the missing men was not allowed to file a missing persons report in the province, Jiangxi, where the factory is located, and police have not returned calls about the missing men.
• The Ivanka Trump brand declined to comment.

The working conditions report from the watchdog group was set to come out in a month, and is to allege low pay, excessive working hours, and misuse of student interns. Other brand names in the same factory: Marc Fisher, Nine West, and Easy Spirit. The watchdog group's work led Walt Disney Co. to stop using a toy maker in Shenzhen last year.

The context, per the AP: "The arrest and disappearances come amid a crackdown on perceived threats to the stability of China's ruling Communist Party, particularly from sources with foreign ties such as China Labor Watch."
