Should the US invade China and liberate all the 12 year old girls from the Walmart concentration-factories?

From a humanitarian standpoint, wouldn't it be right for the US to invade China and free all the 12 year old girls from China's system of slavery that forces the young girls to work in factories hundreds of miles from their homes for up to 18 hours per day for about 15 cents per hour in filthy conditions that would get their employers sued out of business in the USA?
