Asian markets mostly rose again on Tuesday with Hong Kong resuming a rally towards its record high while the dollar struggled to recover from further losses against major peers.
While there were few leads from Wall Street owing to a holiday, investors continued to push into equity markets in Asia to maintain a healthy start to 2018, with Hong Kong skirting its all-time high.
The Hang Seng Index sank on Monday for the first time this year as a record-breaking 14-day surge came to an end on profit-taking.
However, the optimism running through global markets, combined with a flood of cash from mainland Chinese investors, has fired up buying in the financial hub.
In mid-morning trade the HSI was up 0.8 percent -- putting it about 400 points short of its October 2007 peak.
Shanghai added 0.2 percent and Seoul was also 0.2 percent higher while Wellington, Manila and Jakarta also rallied.
But Sydney slipped 0.2 percent, while Singapore and Taipei eased 0.1 percent.
With confidence in the global economy improving and central banks beginning to shift their policy stance away from crisis-era stimulus, the dollar has suffered weeks of selling pressure, with the euro and pound the main winners.
The European single currency surged last week on the back of news that German Chancellor Angela Merkel was close to a coalition deal that will end months of uncertainty in the region's top economy.
And on Monday it almost broke $1.23 for the first time since December 2014 on strong economic data and after a key member of the European Central Bank hinted that it could start cutting back its bond-buying stimulus by September.

And despite uncertainty over Brexit, the pound is also sitting around levels against the dollar last touched in June 2016, when Britain voted to leave the European Union.
Stephen Innes, head of Asia-Pacific trading at OANDA, warned the greenback could face further selling.
"With the dollar trading 'three sheets to the wind' and 'wobbling like a drunken sailor', there is a stronger chance that panic dollar selling will ensue and hammer the dollar lower," he said.
The yuan extended Monday's advance that followed news Germany's central bank would include the Chinese currency in its own reserves, the latest step towards its internationalisation.
The currency is at a two-year high after Bundesbank board member Andreas Dombret's comments. The announcement follows the International Monetary Fund's decision in 2016 to include the yuan in its elite basket of currencies.
On oil markets Brent held above the $70 mark but was facing profit-taking pressure after recent gains, with dealers also concerned that Russia could review its role in an output freeze with OPEC owing to the improving prices.
Shane Chanel, equities and derivatives adviser at ASR Wealth Advisers, said: "I believe there is still further short-term upside. However, I think it's difficult to see prices going much higher from here.
"If we continue to hear the rhetoric of an end to production cuts, the free-for-all approach could see Brent and WTI tumbling back to the $50 level in the second half of 2018."
