The EU has begun the process of imposing trade sanctions on Cambodia by suspending Cambodia’s duty-free trade access. However, many union leaders are concerned that imposing this sanction would encourage large clothing brands to move their manufacturing elsewhere, thus worsening conditions for factory workers. Workers in this industry in Cambodia are frequently forced to work overtime, and in unsafe conditions. Since this issue was brought to light, various initiatives have improved workers’ safety and wages slightly, however the changes have not been sufficient enough for the EU to not impose sanctions on the country.
