MSCI's broadest index of Asia-Pacific shares outside Japan fell 2% in early Asian trading hours, the first daily decline in a week. Japan's Nikkei tumbled 2.4%.

MSCI's broadest index of Asia-Pacific shares outside Japan rose 0.52%, although trading was thin with Japanese and Korean markets closed for public holidays.
