Taiwan Investigating Mainland Dinghy Defector Claim

Taiwan's defence minister on Monday said authorities were investigating whether a man from mainland China had managed to cross the Taiwan Strait in a rubber dinghy in a bid to seek political sanctuary.

On Saturday, police said a man surnamed Zhou had been detained in Taichung city's harbour after locals spotted him near a dyke and said he was behaving suspiciously.

Police said the man told them he had travelled from Fujian on the mainland’s southeastern coast in a rubber dinghy fitted with an outboard motor and 90 liters of fuel.

The man said he wanted to move to Taiwan to seek "freedom and democracy", police said.

Defense Minister Chiu Kuo-cheng said "shortcomings" in how the Taiwan Strait is policed were being investigated because of the man's journey.

"We will get in touch with the coastguard, we will notify each other when there is a situation, to find out the reasons and make improvements," Chiu told reporters on Monday.

The Taiwan Strait is one of the world's most heavily policed waterways.

Navy and coastguard vessels from both sides keep a close eye on the 180 kilometre strait.

The island does not recognise the concept of asylum, partly because it fears infiltration by mainland agents and also because it wants to discourage any influx during times of crises.

Illegal immigrants from the mainland have been returned, but Taipei does sometimes turn a blind eye to dissidents.

Over the years some Chinese refugees have been quietly granted permission to stay, while Taiwan has also welcomed Hong Kongers trying to escape Beijing's crackdown in the restless financial hub. (AFP)
