BEIJING — China's exports rose sharply in June while imports declined unexpectedly, official figures showed on Friday, in further evidence that the world's second-largest economy is charting an uneven recovery.

Officials in China are grappling with a real estate debt crisis, weakening consumption, an aging population and geopolitical tensions overseas.

And the latest figures come ahead of a key conclave of leaders in Beijing next week, with all eyes on how they might kick-start lackluster growth.

That meeting will kick off the same day that China is expected to release its economic growth figures for the second quarter.

On Friday, China's customs department said overseas sales of products and services overseas surged 8.6 percent on-year, up from 7.6 percent in May and better than the 8-percent forecast in a survey of analysts by Bloomberg.

Exports have historically served as an important economic engine in China, having a direct impact on employment for thousands of companies.

June's reading marked a third consecutive rise, after a year-on-year decline in March.

However, imports unexpectedly dropped 2.3 percent, the data showed, reversing May's 1.8-percent growth and much worse than the 2.5 percent expected.

"This reflects the economic condition in China, with weak domestic demand and strong production capacity relying on exports," Zhiwei Zhang, president and chief economist at Pinpoint Asset Management, said in a note.

"The sustainability of strong exports is a major risk for China's economy in the second half of the year," he added.

Economists at Goldman Sachs also said that "with healthy ex-China demand and Chinese products extremely competitive, exports are likely to stay strong in coming months."

But they warned of "downside risks to exports in 2025 and 2026" if former US president Donald Trump is reelected in November and slaps "large tariffs on all imports of Chinese goods, as he has suggested in recent months."

Despite mounting geopolitical rivalry, Chinese exports to the United States remained robust in June, rising 6.6 percent, Friday's data showed.

And those to the European Union increased by the same amount, despite mounting trade tensions after the bloc imposed up to 38 percent additional customs duties on imports of Chinese electric vehicles.

Brussels accuses Beijing of having illegally favored its manufacturers with subsidies.

And trade between China and Russia rose by 3.4 percent year on year, according to Agence France-Presse (AFP) calculations based on official data.

China-Russia trade has boomed since the Ukraine invasion which Beijing has never condemned and hit $240 billion in 2023, according to Chinese customs figures.
