Recent luxury products

I think most of you know this, for those who don't - america imposed 245% tarrifs on china, so the Chinese are selling all the replicas of top luxury brands such as nike, dior, gucci, louis vuitton etc, you guys think those are real? Because the limited edition nike shoes that go for 10 grand are there on Chinese websites for 50$??, a lot of people commented that they are not exactly fake because china is the manufacturer for all those products although companies say it isn't true, thoughts?
