@Maggiethecat the workers they send are treated like shit and some of them may not be Chinese - they could be N Korean.
Local retailers and service providers will think that the workers are totally being nasty and bigoted because they don't spend money in the local economy, when partially the reason is that they aren't earning enough.
The Chinese have done similar in African nations and former Soviet states.
I learnt about it very briefly about 12 years ago and then more recent then that saw some documentaries - I think on Al Jazeera - about what they were doing.
It has been mentioned in the Western mainstream media but normally because countries like US and the old colonial powers feel threatened by the fact that the Chinese are "investing" in countries they use to have a very strong sphere of influence in. The language the Western media use is one of entitlement - they think they are entitled to the governments in Africa, Asia, former Soviet states, the Caribbean and even Oceania only looking to the US and/or old colonial powers for investment or buying of resources.
