Mainland Chinese stocks jumped at the close on Monday afternoon, as data showed that the country's industrial output and retail sales rose more than expected in November.
The Shanghai composite rose 0.56% to 2,984.39, as the Shenzhen component jumped 1.54% to 10,158.24 and Shenzhen composite bounced 1.56% to 1,686.41. Shenzhen's Nasdaq-style start-up board ChiNext soared almost 2% to 2,090.14. Hong Kong's Hang Seng index, however, was down 0.34% during its last hour of trading.
The country's industrial production rose 6.2% year-on-year in November, according to China's National Bureau of Statistics, above a Reuters forecast of a 5.0% growth. Retail sales rose 8.0% year-on-year, also above expectations of a 7.6% growth.
Meanwhile, Asian markets had a mixed reaction to news that China and the U.S. announced they were finally set to sign off on a phase one trade agreement.
Australia's S&P/ASX 200 led stocks in the region, jumping 1.63% to 6,849.70, buoyed by banks and major miners.
But Japan's Nikkei 225 edged down 0.29% to 23,952.35 after a strong rally on Friday, and the Topix index declined 0.18% to 1,736.87. Autos fell, reversing gains they made last week on the back of Brexit optimism.
Over in South Korea, the Kospi edged down 0.10% to 2,168.15

U.S. Trade Representative Robert Lighthizer said on Sunday that the phase one U.S.-China trade deal reached on Friday is "totally done," and it will nearly double U.S. exports to China over the next two years.
U.S. and Chinese officials announced on Friday that the countries had reached a phase one agreement after a contentious 18-month trade war. China agreed to billions of dollars in agricultural purchases from the U.S., while U.S. President Donald Trump vowed to not pursue a new round of tariffs that had been scheduled for Sunday. The two major economies plan to sign the partial accord in the first week of January.
U.S. stocks didn't move much by the Friday close after those trade developments. The Dow Jones Industrial Average ended the day just 3.33 points higher at 28,135.38. The S&P 500 closed just above the flatline at 3,168.80 while the Nasdaq Composite gained 0.2% to 8,734.88.
Analysts advised caution on the upbeat trade news.
John Bromhead, foreign exchange strategist at ANZ Research, said: "The US and China reach another trade agreement but markets are quick to question the level of positivity emanating from the announcement."
"The announcement is a step in the right direction for the two nations, but does not completely reduce the chances of trade disputes between the two nations in the year," he said, adding that there have been no indications from the U.S. that there will be a further rollback in tariffs in the future.
"A trade disaster averted, but nowhere in the vicinity of a global trade break-through that 'lifts all boats'; in fact, not even trade uncertainty is completely lifted," Vishnu Varathan, head of economics and strategy at Mizuho Bank, wrote in a note. "The wider point is that a lot of work is left to be done on US-China relations."
Apple led Friday's slight gains, rising 1.4% to a record after news of the trade agreement was announced. Some of the tariffs set to take effect Sunday would have impacted some of Apple's key products, including the iPhone.
Over in Asia, shares of Apple suppliers were watched for any optimism on that development.
The U.S. dollar index, which tracks the greenback against a basket of its peers, was last at 96.964 after seeing highs of 97.158 earlier.
Oil prices declined in afternoon trade during Asian hours: Global benchmark Brent edged down to $65.15 per barrel while U.S. crude was down 0.13% at $59.98.
