Asian shares mainly drifted lower on Tuesday as investors continued to fret over China Evergrande Group's unsolved debt crisis and eyed the potential impact of a widening power shortage in China.

MSCI's broadest index of Asia-Pacific shares outside Japan was 0.13% lower on Tuesday, following a mixed session on Wall Street

In early trade on Tuesday, Australia's benchmark S&P/ASX200 index was down nearly 1%, while Japan's Nikkei was off 0.6%.

China's blue chip index CSI300 edged up 0.1% at the open, as Hong Kong's Hang Seng Index gained 0.44%.

The future of Evergrande, the world's most indebted property developer, is being forensically scrutinised by investors after the company last Friday did not meet a deadline to make an interest payment to offshore bond holders.

Evergrande has 30 days to make the payment before it falls into default and Shenzen authorities are now investigating the company's wealth management unit.

Without making reference to Evergrande, the People's Bank of China (PBOC) said on Monday in a statement posted to its website that it would "safeguard the legitimate rights of housing consumers".

Widening power shortages in China, meanwhile, halted production at a number of factories including suppliers to Apple Inc and Tesla Inc and are expected to hit the country's manufacturing sector and associated supply chains.

Analysts cautioned the ongoing blackouts could affect the country's listed industrial stocks.

On Wall Street, the Dow Jones Industrial Average rose 144.36 points, or 0.41%, to 34,942.36, the S&P 500 lost 4.57 points, or 0.10%, to 4,450.91 and the Nasdaq Composite dropped 68.29 points, or 0.45%, to 14,979.41.

Rising bond yields prompted a shift from growth to cyclical stocks in the United States, in a move that analysts expect could become more permanent after a prolonged period of suppressed bond yields.

US Treasury yields soared to a three-month high, touching 1.516% overnight following the Federal Reserve's move last week to indicate fiscal stimulus could be tapered asearly as November.
