I agree that the weaker USD is having an effect on the Gold price, the DXY shot up hugely last and this year and has gradually deflated - Bill Gross picked that one out (I think I might have done it before him):
China - is rebalancing and it will take time - hence selling down their US treasuries and perhaps another country taking over. Personally, I think this will still be good for commodities as a whole:
Asia - I think the possible trade agreements will be good for Asia and we could hopefully see some commodity buying (good for Australia) for infrastructure developments - needed in India and Indonesia and elsewhere - Also the populous are Gold buyers! Hefty gold buyers...
Greece? Will there be any contagion and how will that affect the bond markets? Still the same, still worried.
