China, Southeast Asia's largest trading partner, grew by 6% in the fourth quarter, in line with market expectations, suggesting the world's second-largest economy was stabilising.
Data also showed that December's industrial output grew 6.9% from a year earlier, the strongest pace in nine months, while retail sales rose 8.0%. Fixed-asset investment for the full year jumped 5.4%.
"The latest slew of economic data suggests that the global economy is stabilising and poised for a recovery amid de-escalating U.S.-China trade tensions," Han Tan, market analyst at FXTM, said in a note.
"Such an environment should also offer emerging markets the chance to find a more stable footing and provide room for riskier assets to advance."
Philippine shares climbed 0.9% in their best session in two weeks, with Jollibee Foods Corp topping the benchmark index. The main index shed 0.7% for the week.

Kasikornbank Pcl gained 2.5% and Advanced Info Service Pcl firmed 1.9%.

The city-state's exports posted a surprise rebound in December after nine months of contraction, partly boosted by a sharp rise in pharmaceutical shipments.
However, economists said further declines in electronics exports did not yet indicate the recovery could be sustained.
