In Australia, the benchmark S&P/ASX 200 fell 1.6% to close at 5,879.10, marking its biggest fall in more than two weeks.

Shares in Chinese water purification company Ozner Water International rose by more than 15% following a five-week long suspension.
The firm had been accused of making “false and misleading representations” over its profitability by short-seller Glaucus Research last month.
The allegations caused Ozner`s shares to lose a fifth of its value before trading was halted.
On Wednesday, Ozner addressed Glaucus Research`s claims as “unfounded allegations” in a detailed statement to the Hong Kong stock exchange.
“We will not tolerate what seems to be an outright malicious attack on the company for personal gains which harms the company`s reputation and business prospects,” it said.
