Strong FAI is bullish for commodities demand as increased industrial activity and construction gobbles up more cement, iron ore, crude oil and copper.

FORBES: China Bull Still Runs Strong Even If Slower

Although Brazil enjoys a big overall trade surplus with China, most of its exports are of commodities (mainly iron ore, soya beans and crude oil).

ECONOMIST: Brazil��s trade policy

While iron ore, metallurgical coal, copper, and crude oil faced temporary supply side disruptions that boosted prices excessively, the longer-term, commodity super cycle remains intact.
