China's economy is expected to have seen moderate growth in the third quarter, according to an AFP survey ahead of data this week, while experts warn that there were still significant hurdles for its recovery.

Authorities have been seeking ways to reinvigorate activity in an economy grappling with a major property crisis and weaker consumption since Beijing abolished its strict zero-Covid policy last year.

Analysts polled by AFP saw an average 4.3 percent on-year growth in gross domestic product in July-September, falling short of more ambitious projections of a sustained recovery.

"Troubles in the property sector have spilled over into wider consumer activity and translated into consumers still spending a smaller share of their income relative to pre-Covid," Capital Economics' Sheana Yue said.

Beijing has set a goal of around five percent growth for 2023 — one of its lowest targets in years following decades of breakneck expansion.

And that goal "is not a strong number considering last year's low base", Gene Ma of the Institute of International Finance said. "The main challenge is still housing."

While real estate was once a driving force for the world's number two economy, many developers are now fighting for survival — exacerbating a crisis of confidence among potential buyers.

"Given the large stock of empty homes, aging population, and the end of speculation fever, we expect home sales to remain subdued for years to come," said Ma.

The newest quarterly figures are due to be released on Wednesday, the same day that a slew of world leaders including Russian President Vladimir Putin arrive in Beijing for a summit on China's Belt and Road — potentially meaning they could be delayed.

Authorities last year postponed the release of third-quarter figures ahead of a major political conference, without providing a reason.

Experts say China is on track to reach its modest goal for the year, with AFP's survey of analysts forecasting annual growth of 4.92 percent.
