(Reuters) -Chinese e-commerce firm PDD Holdings beat market estimates for quarterly revenue on Monday, signaling a rebound in domestic demand and improved growth in its international business despite global trade uncertainties.

The Chinese owner of bargain-shopping app Temu reported a smaller-than-expected profit decline in 2Q despite revenue growth hitting a three-and-a-half-year low as tariffs and increased support for domestic merchants weighed on profitability.

(Yicai) Aug. 26 -- PDD Holdings reported better-than-expected earnings in the second quarter of the year. However, the co-chief executive officer of the Chinese owner of discount shopping sites Temu and Pinduoduo warned about unsustainable performance.
