Asian stocks fell in cautious trading on Thursday after bailout negotiations between debt-ridden Greece and its international creditors hit a stalemate overnight, making the country’s future in the European Union shaky. Greece is on the verge of defaulting on its debt if a deal fails to materialize before the June 30 deadline, when Greece has to repay 1.6 billion euros ($1.79 billion) to the International Monetary Fund. European Union leaders are set to meet again later in the day to discuss a cash-for-reform deal.
