Rferl on 28th June reported that a US State Department report says that Belarus, Iran, Russia, and Turkmenistan remain among the worst offenders of human trafficking and forced labour. The report evaluates 187 countries and territories and ranks them into 4 tiers (Tier 1, Tier 2, Tier 2 Watch List, and Tier 3), with Tier 1 being the best and Tier 3 the worst. Russia, Belarus, Iran, and Turkmenistan were among 22 countries ranked as Tier 3; others included Burma/Myanmar, China, North Korea, Syria, and Venezuela. The report also listed 43 countries in danger of being downgraded to Tier 3 in future years – the Tier 2 Watch List includes Bosnia-Herzegovina, Kyrgyzstan, Montenegro, Tajikistan, and Uzbekistan, along with EU member state Hungary.
