China's infalation and oil prices. Oil prices and Dollar relataionships

Hello,

It is great to find community like this and I am glad to be part of it now. Hope some of you will help me. without further ado, I have few question that I would like to clear out.

first is: why oil prices drop when China inflation rises?
second: does the inverse correlation between oil and dollar still exists?

hope to have great discussion:)
