It could also be a play to squeeze China or similar nation dependent on middle east oil. USA semicon production not ready, if there were signals that China was ready for a play on Taiwan maybe this is a gambit to buy some time.
Is China really dependent on middle-east oil? I read that they had been diversifying in preparation for an energy resource fight for some time now. For example, they've massively invested in Solar power generation, are building a 300-400 billion dollar gas pipeline from Russia, already buy a lot of oil to from Russia, and also purchased from Venezuela (though how that's going now is anybody's guess). They also have a good relationship with most of the players in the middle-east and helped repair ties between the Saudis and the Iranians.
Inflation is about what goes on inside the country. So you can have inflation internally while the domestic currency strengthens against foreign currencies, and vice versa.
If your currency is falling against foreign currencies but prices are also dropping domestically, you get deflation. This was happening in China a couple of years ago, and they were exporting this deflation to other countries.
