Canada and China communicate a lot. Canada buys China's cheap products all the time. Both countries are constantly trying to keep up with the economy, their products are in high demand. Canada doesn't exactly make Beijing's child labor rate go down. Since Canada keeps buying from China that just means the shops stay open, the kids keep working, and the kids keep not getting paid are treated properly. Beijing's current population is around 20 million people. Probably about a quarter of that number would be children under the age of eighteen, now not all of these children are involved in child labor but most of them are possible victims. Beijing is a very busy place and it would be very hard to stop all of this in its tracks.There are many NGOs are involved in helping stop human rights violations like the Oprah angels network, they donated to many schools, donating money,  school supplies, and many more useful things. There is an organization called the underground railroad organization. They dedicate there time to stopping slavery all around the world helping people escape slavery and help people learn about it, so they can be aware and also help stop slavery in their own unique ways.
