(Reuters) - China's economy grew at a slightly faster pace than expected in the second quarter, showing resilience in the face of U.S. tariffs, though analysts warn of intensifying headwinds that will ramp up pressure on policymakers to roll out more stimulus.

Data on Tuesday showed China's gross domestic product (GDP) grew 5.2% in the April-June quarter from a year earlier, slowing from 5.4% in the first quarter, but just ahead of analysts' expectations in a Reuters poll for a rise of 5.1%.

COMMENTARY

JEFF NG, HEAD OF ASIA MACRO STRATEGY, SMBC, SINGAPORE

"The market reaction was quite muted because of the fact that expectations were already there for China to grow by more than 5%.

"Growth has been supported by front-loading... (but) I think we're still staring at a slowdown once the tariffs come into fruition.

"The domestic economy and retail sales, of course, it'll still be dragged by concerns. The sentiment isn't that great, but at least I see some signs of it bottoming out."

BACKGROUND

* U.S. President Donald Trump's global trade war has added a significant new layer of risk for China's economy, which has been struggling to mount a solid recovery due to a prolonged property crisis, deflationary pressures and low consumer confidence.

* The world's second-biggest economy has so far avoided a sharp slowdown this year due partly to a fragile U.S.-China trade truce and policy support measures.

* China's exports regained some momentum in June while imports rebounded, as firms rushed out shipments to capitalise on the tariff truce between Beijing and Washington ahead of a looming August deadline.

* Beijing has ramped up infrastructure spending and consumer subsidies, alongside steady monetary easing. In May, the central bank cut interest rates and injected liquidity as part of broader efforts to cushion the economy from Trump's trade tariffs.

* But analysts say stimulus alone may not be enough to tackle entrenched deflationary pressures, with producer prices in June falling at their fastest pace in nearly two years.

* China has set an ambitious 2025 growth target of "around 5%", though the trade war with the United States has already prompted many analysts to sharply downgrade their GDP forecasts for this year.

* For the whole of 2025, China's GDP growth is forecast to cool to 4.6% - falling short of the official goal - from last year's 5.0% and ease further to 4.2% in 2026, according to a Reuters poll.
