DATA DUMP: Japan released revised first-quarter data that showed Asia's second-largest economy expanded an annualized 1 percent, a significant drop from last month's initial 2.2 percent estimate, according to Kyodo News.

ECB MEETS: Investors will be keeping an eye on the European Central Bank's meeting and news conference later in the day, where policymakers are expected to sketch out their latest plans for the bank's bond-buying stimulus program.

"However, as one half of the equation in raising global growth outlook, European markets' performance post the ECB meeting and UK election could still have an impact on emerging Asian markets."
