Prosecutors from around the world joined hands at a three-day summit in London last week that was intended to bolster efforts against modern slavery, the Thomson Reuters Foundation reported. Britain’s Crown Protection Service (CPS) said the prosecutors intend to collaborate more closely to convict those engaging in slavery and human trafficking. The prosecutors also planned to discuss bettering attempts to seize illegal profits from trafficking and protecting witnesses and victims to obtain evidence. Countries present at the summit included Albania, Argentina, Greece, Nigeria, Poland, Romania, and Sudan, and the Netherlands. According to CPS, both traffickers and victims hail from the latter two countries. According to the International Labour Organization and Walk Free Foundation, more than 40 million people were living in modern slavery in 2017. Human trafficking reportedly generates $150 billion annually.
