ASIA-Shares may struggle despite Wall St rally

WELLINGTON, Dec 1 (Reuters) - Asian shares may struggle on Monday despite Wall St posting its best week in 30 years last week, with investors tempted to book profits as they brace for more economic bad news in the days ahead.

 Australian shares opened down, and Japanese stocks were also indicated lower, ahead of a host of U.S. data which is expected to paint a picture of a worsening economic situation. Among the scheduled data are U.S. jobs, car sales and manufacturing.

 Investors will also be cautious on Monday after Chinese President Hu Jintao warned that the world's fourth-largest economy was being threatened by the economic downturn.

 Commodity prices were mixed on Friday, with oil rising and copper falling, while the U.S. dollar gained against the euro as risk-averse investors piled into U.S. Treasuries.
