Taiwan prosecutors have charged a Taipei company and its two owners with illegally operating as a front for a mainland Chinese electronics maker, a case that is bad news for Chinese firms trying to use local shell companies to dodge cross-strait investment rules.

Prosecutors say Feng Yaoxian, who also serves as global sales vice president for China's Hongwei Technology, and his wife Zheng Huiyue set up Taipei-based Yaoxun International after Taiwan's investment regulators told them a joint venture with the Chinese company could not legally open a branch there. Instead, the couple ran Yaoxun on paper as an independent Taiwan business while actually handling marketing, sales, and hiring for Hongwei's wireless and semiconductor products.

Investigators found Hongwei wired the couple money over more than a decade, including a lump sum of roughly NT$9.3 million between 2009 and 2023, to cover Yaoxun's staff salaries and operating costs — money prosecutors say shows the Taiwan company was really just Hongwei's unauthorized local operation.

Taiwan law bars mainland Chinese companies, or firms they control through third regions, from doing business on the island without setting up an approved branch or office, a rule meant to keep Beijing-linked firms from operating unchecked in Taiwan's economy.

Outlook: The case heads to trial, and it is likely to draw more scrutiny toward other Taiwan shell companies suspected of fronting for mainland Chinese business interests.
