Asian stocks have mostly drifted lower as investors grew cautious ahead of a critical European Union summit later this week where Greek leaders will attempt to renegotiate some terms of the country's international bailout.
Japan's Nikkei 225 index was 0.1% lower at 8,785.10 and South Korea's Kospi slid 1.7% to 1,816.11. Hong Kong's Hang Seng was flat at 18,998.78 as it fluctuated between gains and losses. Australia's S&P/ASX 200 was down 1.2% at 3,999.40.
Mainland China's Shanghai Composite Index fell as did benchmarks in Singapore and Taiwan.
Investor pessimism about the state of the world economy prevailed even as the leaders of France, Germany, Italy and Spain agreed over the weekend to push for a growth package worth up to 130 billion euro (£105 billion) at the European Union summit scheduled for June 28-29 in Brussels.
The meeting is aimed at kick-starting the economy and safeguarding the currency bloc.
The summit will prove a key test of Greek leaders' pledges to loosen the terms of the country's bailout. Greece's new government said at the weekend it would seek to repeal some taxes, halt layoffs and extend a deadline for tough austerity measures by two years.
But Germany, the biggest single contributor to the bailout, says Athens must stick to the current targets.
Previous summits and meetings have failed to deliver a "credible set of solutions to the Eurozone crisis", strategists at Credit Agricole CIB said, so "markets are likely to remain relatively range bound ahead of the summit".
