(CNN)Myanmar, Sudan and Haiti are currently among the worst offenders for human trafficking, according to a new report published today by the U.S. State Department.
The three nations were among 27 to be downgraded in this year's annual Trafficking in Persons -- or TIP -- report.
What the TIP Tiers mean
Tier 1: Governments fully comply with the Trafficking Victims Protection Act's (TVPA) minimum standards.
Tier 2: Governments do not fully comply, but are making significant efforts to bring themselves into compliance.
Tier 2 Watch List: Governments do not fully comply, but are making significant efforts to bring themselves into compliance, as well as other negative indicators.
Tier 3: Governments do not fully comply and are not making significant efforts to do so.

After two years, Thailand moved off the bottom rung due to the government's "significant efforts" to eliminate trafficking. Though the report says there's still "widespread forced labor" in the country's seafood sector.
And on the same day new President Rodrigo Duterte assumed power, the Philippines moved up to become a Tier 1 nation. However, sex trafficking is still considered a "significant problem."
