Foreign buyers will throng the vast halls of China's biggest trade expo from Monday, scouting for deals on Chinese goods that U.S. and European governments complain are flooding global markets. The 135th Canton Fair comes as China is making a strategic policy shift, accelerating resource distribution towards its manufacturing complex and away from its crisis-hit property sector, in the hope that it can move up the value scale. This is causing alarm in Washington and Brussels, especially over what China calls the "new three" industries of electric vehicles, batteries and solar energy, where the world's second-largest economy is becoming a dominant export power.
