Every year, tens of thousands of migrant workers from Kyrgyzstan travel to the Central Asian economic powerhouse of Kazakhstan in search of employment. Thousands of these migrant workers, often together with their children, find work in tobacco farming. Human Rights Watch research in 2009 documented abuse and exploitation of many migrant workers by tobacco farm owners who employ them for seasonal work. Tobacco farm owners in Kazakhstan contract with and supply tobacco to Philip Morris Kazakhstan (PMK), a subsidiary of Philip Morris International (PMI), one of the world's largest tobacco companies.
