Asian shares mainly rose on Tuesday, tracking gains on Wall Street and following a surge in Shanghai the previous day fuelled by speculation China plans to overhaul its state-owned enterprises.
Tokyo gained 0.54 percent at the open, Hong Kong climbed 1.11 percent and Seoul added 0.81 percent, while Sydney dipped 0.65 percent.
Shanghai added 0.15 percent after surging Monday on news Beijing is making fresh moves to support equities and hopes for an overhaul of the country's inefficient government-backed companies.
The rise in equities, which closed up almost five percent, marked the broadest rally in Chinese shares in history, analysts said, with only two out of some 1,400 listed companies falling.
The news followed disappointing trade and inflation data from Asia's largest economy over the weekend, which spurred hopes in some corners that Beijing will also unleash fresh monetary stimulus.
"One of the biggest fears in the marketplace is not so much the Fed, it's the slowdown in China," Andrew Brenner, head of international fixed income for National Alliance Capital Markets, told Bloomberg News.
"If all of a sudden people think the Chinese are going to have serious stimulus, that's going to turn things around."

"We're dealing with an increased likelihood that the Fed will start raising rates in September... How the market contends with that is problematic," he told Bloomberg News.
