Copper and China CZN?

Hello Everyone. Thanks for sharing this community with me, I'm new here, sorry I'm still getting around to putting some pizazz in my profile.

Meanwhile, I thought I'd start out w/ a light discussion about Copper and it's relationship w/ China, I'm trying to improve my copper trading.

One thing that I do like about copper is that it does not seem to have any heavy relationships on MRCI's inter-market correlations. But, then I noticed copper jump hard with an economic report.

So, I dumped watching the DXY/$USDOLLAR as an indicator and starting watching $CZN; seems to have a positive correlation to copper.

My question : is this the best index to choose? I think I'm more interested in the Shenzhen area of china rather than the whole. I can't seem to find much information on the subject so i thought I'd start here.

Any insights would be welcome!
