WRAPUP 2-China's economy perks up but dogged by property crisis

* Key August indicators better-than-expected

* Retail sales growth quickest in 6 months

* Property slump a significant headache

BEIJING, Sept 16 (Reuters) - China's economy showed surprising resilience in August, with faster-than-expected growth in factory output and retail sales shoring up a fragile recovery, but a deepening property slump weighed on the outlook.

The better-than-expected figures show the world's second-largest economy is gaining some steam, after narrowly escaping a contraction in the June quarter and lifting recovery prospects marginally for the rest of the year.

Industrial output grew 4.2% in August from a year earlier, the fastest pace since March, according to the National Bureau of Statistics (NBS). That beat a 3.8% increase expected by analysts in a Reuters poll and July's 3.8% expansion.

Retail sales rose 5.4% from a year ago, the quickest in six months and also beating forecasts for 3.5% growth and the 2.7% gain in July.

"This is due to a lower base for comparison – the Delta wave was weighing on economic activity in August 2021," said Julian Evans-Pritchard, a China economist at Capital Economics.

Although the upbeat data lifts some of the gloom hanging over the sluggish recovery, which had been clouded by weak trade data and slow credit growth, Evans-Pritchard does not expect the strength to sustain into September.

"And while the current virus wave may have peaked, activity is set to remain weak over the coming months amid the deepening property downturn, softening exports and recurring COVID-19 disruptions," he said.

The auto industry was a big driver of both factory output and retail sales, with new energy vehicle production surging 117%, helped by government incentives for cleaner cars.

However, outages at several state oil refiners and independent plants and thinning margins kept crude throughput near two-year lows. Daily coal output also slipped to a three-month low.

PROPERTY CRISIS

With few signs China will significantly ease zero-COVID soon, some analysts expect the economy to grow just 3% this year, which would be the slowest since 1976, excluding the 2.2% expansion during the initial COVID hit in 2020.

"Since the start of this year, the situation facing economic development has become more complex and severe than that in 2020," NBS spokesperson Fu Linghui said, citing the risk of a global downturn and challenges around China's COVID controls. However, he said recent policy support was having some effect.

In contrast to the upbeat activity data, the property sector contracted further in August as home prices, investment and sales extended losses.
