Asian markets rose overnight following a record-breaking session on Wall Street.
The S&P 500 surged to its first-ever close above the 4,000 mark, lifted by gains in Microsoft, Amazon and Alphabet, as well as optimism about a recovering US economy.
Investors were buoyed by US President Joe Biden's $2.3 trillion infrastructure spending plan.
The Dow Jones and Nasdaq were both higher, while the S&P 500 gained 1.18% to 4,019.87.

"We're still bullish for this year, and we think that with stimulus, with the Fed committed to being dovish, with the economy reopening due to more of the US getting vaccinated, overall you're going see corporate earnings do pretty well," said King Lip, chief investment strategist at Baker Avenue Asset Management in San Francisco.
Microsoft, Amazon, Alphabet and Nvidia jumped 2% or more, with those and other growth stocks showing signs of awakening after lagging in recent weeks behind so-called value stocks expected to outperform as the economy recovers from the coronavirus pandemic.
Google-parent Alphabet's 3.3% rally left it at its highest close ever.
Data showed the number of Americans filing new claims for unemployment benefits rose unexpectedly last week. However, other data showed a measure of manufacturing activity soared to its strongest level in more than 37 years in March, with employment at factories the highest since February 2018.
Markets in Tokyo and Seoul were up more than 1%, while Shanghai was also in positive territory.
