Stocks in Asia mostly slipped on Wednesday after U.S. President Donald Trump said overnight that he may delay a trade deal with China till after the 2020 U.S. presidential election.

Shares in Australia led losses among the region’s major markets, with the S&P/ASX 200 declining more 1.58% to close at 6,606.50 as shares of major miner BHP plunged 2.49%.

The Australian economy grew 1.7% on a seasonally adjusted basis year-on-year in the September quarter, data from the Australian Bureau of Statistics showed on Wednesday.

“The economy has continued to grow, however the rate of growth remains well below the long run average,” Bruce Hockman, chief economist for the ABS, said in a statement.

In Japan, the Nikkei 225 fell 1.05% to close at 23,135.23 as shares of index heavyweight Fast Retailing plummeted 5.21%. The Topix index also declined 0.2% to end its trading day at 1,703.27.

Mainland Chinese stocks were mixed on the day, with the Shanghai composite down 0.23% to about 2,878.12 while the Shenzhen component was up 0.31% to 9,687.95. The Shenzhen composite also rose 0.199% to approximately 1,608.52. Hong Kong’s Hang Seng index declined 1.16%, as of its final hour of trading.

South Korea’s Kospi ended its trading day 0.73% lower at 2,068.89, as shares of chipmaker SK Hynix fell 1.27% — following overnight declines of NvidiaMicron and Advanced Micro Devices on Wall Street.

Investors have been anticipating a “phase one” trade deal between Washington and Beijing to be inked, ahead of a closely watched date of Dec. 15, when additional tariffs on Chinese exports to the U.S. are set to kick in.

But Trump told reporters on Tuesday: “In some ways, I like the idea of waiting until after the election for the China deal, but they want to make a deal now and we will see whether or not the deal is going to be right.” When asked if he had a deadline for the deal, he added: “I have no deadline, no.”

“Hopefully it’s just negotiating tactics and posturing in the run up to the December 15th deadline and we’ll see some sort of resolution well ahead of … the 12 month timeline,” James Thom, investment director of Asian equities at Aberdeen Standard Investments, told CNBC’s “Squawk Box” on Wednesday.

Even if tariffs do increase come Dec. 15, Thom said: “Who knows how long that will last, there’s always the scope to roll that back.”

Principal Global Investors’ Seema Shah dubbed Trump’s latest comments as a “ploy to regain the upper hand in these negotiations.”

“Just like muscle memory, markets need to learn from experience that there is little to gain from reacting too sharply to Trump’s trade related comments in the run-up to a deal,” Shah, who is chief strategist at Principal Global Investors, said in a note. “In the past 18 months he has clearly demonstrated that this ‘to and fro’ is his preferred form of negotiation.”

Fox News reported that the White House still plans on moving ahead with scheduled Dec. 15 tariffs on Chinese goods notwithstanding recent efforts at a “phase one” trade truce.

Overnight stateside, stocks tumbled amid the trade uncertainty. The Dow Jones Industrial Average fell 280.23 points to close at 27,502.81 while the S&P 500 slipped 0.7% to end its trading day at 3,093.20. The Nasdaq Composite closed about 0.6% at 8,520.64.
