HONG KONG, Aug 7 (Reuters) - China stocks rose for a fourth straight day to close at a 3-1/2-year high on Thursday, as upbeat export data added fuel to the recent market rally despite renewed U.S. tariff threats.
** The Shanghai Composite index .SSEC climbed 0.2% to 3,639.67, the highest such close since December 2021. The blue-chip CSI300 index .CSI300 was little changed.
** China's exports beat forecasts in July with outbound shipments up 7.2% year-on-year, customs data showed, as manufacturers made the most of a tariff truce with the United States.

** Investors remain focused on an August 12 deadline to see if Beijing and Washington will reach a durable tariff agreement.
** "The upward trend is still intact," analysts at Pacific Securities said in a note, adding markets remain optimistic about U.S.-China trade talks while technical indicators continue to show bullish momentum.

** Local developers .HSNP jumped 2.5% as New World Development < 0017.HK> surged as much as 20% on a report of talks that could potentially take it private.
