Asian markets mostly dropped Tuesday as the previous day's euphoria over the China-US trade ceasefire gave way to questions about whether the two can ultimately resolve their differences.
Global investors were given some much-needed Christmas cheer at the weekend after Donald Trump and Xi Jinping called a halt to their painful tariffs battle for 90 days while they try to resolve their differences.
The news lit a fuse under markets after a torrid year that has been dominated by the trade war between the world's top two economies, which many fear will hit global growth.
However, there is concern that the three month grace period will not be enough for them to hammer out agreements on key issues, particularly on intellectual property protection.
"Can the US and China really resolve their differences in 90 days?" asked Rodrigo Catril, senior strategist at National Australia Bank.
"It seems that more details and signs of progress will be needed if the initial trade truce warm fuzzy feeling is to be sustained." Also, later Monday there was uncertainty about Trump's claims in a tweet that China had agreed to slash tariffs on car imports, with two of his top advisers unable to provide clarity on the issue.
"That's what happens when you don't have the detailed negotiations going into the summit" and end up with the "broad swath of a 35,000-foot deal," Bonnie Glaser, a China expert at the Center for Strategic and International Studies in Washington, said.
"It's risky. There's certainly no guarantees that it will produce the outcomes that we want." Hong Kong dipped 0.3 per cent, Tokyo fell 0.7 per cent by lunch, Shanghai was 0.2 per cent off and Sydney lost 0.6 per cent.
Singapore and Seoul each dropped 0.5 percent, while Taipei eased 0.3 per cent though there were gains in Wellington, Manila and Jakarta.
Still, Jeff Kleintop, chief global investment strategist at Schwab Center for Financial Research remained upbeat.
"It's easy to see the trade deal as a half empty (glass) -- that it's just a postponement and that they'll work together but that there really isn't any kind of resolution," he said.
"But I think you can see it as a half glass full." On oil markets both main contracts posted more healthy gains, adding more than one percent, having racked up gains of almost four percent Monday on the trade deal, the Russia-Saudi output agreement and a cut in production in Canada.
Focus is now on a meeting of OPEC and non-OPEC members in Vienna at the weekend, where they will reveal how much and for how long they will reduce as they look to stabilise the crude market.
On currency markets the pound is struggling to bounce back against the dollar as MPs prepare to debate Prime Minister Theresa May's Brexit deal as she struggles to win over enough people to support it.
Failure to push the agreement through parliament could bring down her government, fuelling more uncertainty in the country.
