On 4 August, C4ADS published a report arguing that port state authorities could do more to fight the use of forced labour at sea and human trafficking. It could do this by identifying and disrupting forced labour and its supporting mechanisms at key ports. It finds that, between 2015 and 2020, Taiwan, Singapore, China, and South Africa were the most common port states visited by fishing vessels using forced labour, while Kaohsiung, Singapore, and Cape Town were the individual ports most frequently visited by fishing vessels using forced labour. It says that forced labour in the fishing industry functions by cutting fishers off from the rest of the world. It is the brief interludes during which vessels are at port and subject to greater regulatory oversight that provide the best opportunity for the identification and disruption of ongoing cases of forced labour.
