Chinese police have arrested four employees of Taiwanese iPhone maker Foxconn in circumstances that Taipei called “strange.”
The employees were arrested in Zhengzhou, Henan province, for “breach of trust”, Taiwan's Mainland Affairs Council said in a statement.
The BBC has contacted Foxconn for comment.
The company is the largest maker of iPhones for US tech giant Apple and one of the world's largest employers, with major manufacturing facilities in China.
Taiwanese authorities have suggested that the detentions could be a case of “abuse of power” by Chinese police officers.
And said that this affair undermines the confidence of companies operating in China.
In October last year, Chinese tax and land authorities opened an investigation into the company.
At that time, Foxconn founder Terry Gou was running as an independent candidate in Taiwan's presidential election.
Taiwan has urged its citizens to “avoid all non-essential travel” to the mainland as well as Hong Kong and Macau after China unveiled guidelines in June detailing criminal sanctions against what Beijing described as die-hard “Taiwan independence” separatists.
Foxconn's factory in Zhengzhou is the world's largest iPhone factory, widely known as “iPhone City”.
The company is one of several Taiwanese companies that over the past 40 years have overcome a long-standing geopolitical divide and built factories in China.
