The Global Slavery Index 2018 estimates that on any given day in 2016 there were over 3.8 million people living in conditions of modern slavery in China. Included in the types of slavery prevalent in China is forced labour, with China's unprecedented rise to the world's second largest economy and its domestic economy specialising in the production of labour-intensive, cheap goods for export, increasing the demand for cheap labour. Forced labour occurs in both the manufacturing and construction sectors, as well as more informal industries such as brick kilns and garment facoties. Many women are also tricked in to forced labour as domestic servants, lured by the promise of good jobs with high incomes they instead find themselves confined to the house and forced to work long hours with little or no pay.  Sian Men Mawi legally worked as a maid in Singapore before moving to China, lured by the promise of a lucrative employment contract. She arrived in Guangzhou on a tourist visa. She was enslaved by her agent who locked a number of Myanmar girls in separate houses and rotated them through different jobs, holding their wages and never letting them pay off their debts. Sian Men managed to escape and returned to Myanmar by bus, evading the police who manned checkpoints along the route.
