Asian markets traded higher on 22 May, with the Japanese Nikkei striking a fresh 15-year peak and the Shanghai Composite hitting a new seven-year high, following a strong handover from Wall Street.
The Japanese Nikkei finished 0.30%, or 61.54 points, higher at 20,264.41.
The Shanghai Composite finished 2.83%, or 128.17 points, higher at 4,657.60.
Hong Kong's Hang Seng finished 1.70%, or 469.11 points, higher at 27,992.83.
Australia's S&P/ASX finished 0.04%, or 2.40 points, higher at 5664.70.

India's S&P BSE Sensex finished 0.53%, or 148.15 points, higher at 27,957.50.
The Nikkei has been buoyed by the Japanese economic recovery.
The BoJ left its annual 80tn yen ($662bn) monetary easing programme in place after a two-day meeting. The central bank refrained from announcing more stimulus measures after official data released earlier this week showed that the world's third-largest economy grew more than expected in the first quarter.
Capital Economics said in a note to clients: "The Bank of Japan's more upbeat economic assessment today suggests that the introduction of more stimulus as early as July is off the table. However, we remain convinced that the prospect of prolonged below-target inflation will convince policymakers to step up the pace of easing by October."
Elsewhere, the Shanghai Composite surged as "unused funds from recent new-share listings have been repositioned back into the domestic market", wrote IG's chief market strategist Chris Weston in a note.
Meanwhile, the Sensex was trading comfortably in green territory.
Capital Economics said in a separate note: "As [Indian] Prime Minister [Narendra] Modi's first year in office draws to a close, our view that the economic reform agenda would fall short of (at times frenzied) expectations appears to have been proved correct for the time being.
"Admittedly, PM Modi can point to some successes, most notably on lifting restrictions on foreign investment in some sectors of the economy and on reducing subsidies. But progress on pushing through the "big bang" reforms that many had hoped for, including on land, tax and labour laws, has been underwhelming.
"So far, not enough has been achieved to suggest that India can fulfil its economic potential over the medium term."
