Dec 4 (Reuters) - Australian shares extended losses on Wednesday as a resurgence in concerns about global trade tensions hit Wall Street stocks and weighed on the mining and financials sectors.
Recent optimism the Sino-U.S. trade dispute may be close to a resolution waned as U.S. President Trump suggested the deal might have to wait longer, while Commerce Secretary Wilbur Ross confirmed new tariffs on Chinese imports would take effect on Dec. 15 as scheduled. S&P/ASX 200 index .AXJO slid about 1.4% to 6,620.20 by 2349 GMT, after declining 2.2% in the previous session, where it posted its biggest daily drop in two months.

Heavyweight financial stocks bore the brunt of the sell-off with all constituents in the sub-index .AXFJ trading in the red.
