U.S. President Donald Trump threatened that the U.S. could impose fresh tariffs on Chinese goods and that the two countries still had a "long way to go" in striking out a trade deal.

U.S. retail sales in June increased more than expected, helped by a rise in purchase of motor vehicles, furniture and building materials, among other things.

"While traders see the Federal Reserve interest rate cut this month as a lock, the strength of June data could be enough to dim the hopes for subsequent easing," said Stephen Innes, managing partner at Vanguard Markets Ltd, in a note.

Market participants have benefited over the last year from hopes of dovish action from the Fed, especially when confronted by headwinds from the Sino-U.S. tariff war. The year-long spat between the world's two top economies has caused considerable damage to economic growth worldwide.

Malaysian stocks were down 0.7%, dragged by resource and utility stocks. Petronas Chemical Group lost 3.9%, while electricity generator Tenaga Nasional fell 1.6%.

Indonesian shares <.JKSE> were slightly lower, hurt by losses in telecom and financial stocks.

Indonesia's central bank is widely expected to cut rates on Thursday, according to a Reuters poll, ahead of the anticipated Fed policy easing.

Thai stocks fell, with index heavyweights Bangkok Bank and PTT Exploration and Production down 1% each.

Philippine benchmark <.PSI> ended lower for a second day, hurt by losses in financial and industrial stocks.

Property developer SM Prime holdings fell 1.4%, while International Container Terminal Service was down 1.1%.

Singapore shares <.STI> rose marginally, as the market awaited further direction after disappointing June export data, which followed a contraction in second-quarter GDP.

"The economic data has increasingly favoured easing by the Monetary Authority of Singapore" Prakash Sakpal, an economist at ING group, said in a note.

"Talk of an off-cycle policy adjustment, before the next scheduled semi-annual review in October, has gained traction," he added.
