Trade was at the tops of investors' minds after the Trump administration last week said it will impose a 25 percent tariff on a list of 818 items of Chinese goods worth around $34 billion beginning July 6. Measures affecting an additional 284 products worth $16 billion will be subject to review before taking effect.
In response, China said a 25 percent tariff will be implemented on U.S. goods, including soybeans and electric vehicles, worth $34 billion starting July 6. Another list of U.S. imports worth $16 billion will be subject to review before being applied.
"Although the initial $34 billion is unlikely to have material impact on both economies, it does pose risks to the global recovery and sentiment," Tommy Xie, head of greater China research at OCBC Bank, said in a note.
Despite the latest dust-up on the trade front, U.S. stocks finished the last session well off the day's lows. The Dow Jones industrial average slipped 0.34 percent, or 84.83 points, to close at 25,090.48, after losing as much as 280.93 points earlier.
On the energy front, oil prices extended losses after slumping in the last session ahead of OPEC's meeting in Vienna later this week. The declines also came amid the trade jitters, as energy products had been included in the list of additional U.S. goods that China could target at a later date.
The dollar firmed slightly against a basket of currencies early on Monday, hovering just below the seven-month high of 95.131 touched on Friday amid concerns over trade.
"The reason why the dollar is behaving this way is because while a trade war is bad news for everyone it is even worse for the countries being singled out as many of them rely heavily on U.S. demand," Kathy Lien, managing director of FX strategy at BK Asset Management, said in a note.
