Traders were bracing for a potential escalation in the Sino-U.S. row after President Donald Trump raised the stakes on Friday, saying he is ready to impose tariffs on virtually all Chinese imports to the United States. He also called on Apple to make its products in the United States.
Emerging market stocks lost 1.19 percent for the day.
U.S. stock investors are looking to extend momentum after corporate profits hit a record high in the second quarter, while investors think an Italian debt crisis would spark a conflict with Europe that would hurt the domestic economy.
Congressional Republicans plan to unveil another round of tax cuts this week ahead of the Nov. 6 U.S. elections.
"Markets continue to be under pressure from a whole host of headwinds," said Tim Love, investment director of emerging market equities at fund manager GAM Holding AG.

Shares in Stockholm and the Swedish crown strengthened after the nationalist Sweden Democrats gained less ground than polls had predicted in elections on Sunday.
The latest 14-month low for emerging-market shares came amid turbulence in Argentina, Turkey, Brazil, Russia and South Africa, where currencies have been routed recently.
Some Asian economies are vulnerable, too, Nomura analysts said, with many countries burdened by high private debt. They also noted a "concentration risk" from some of the world's largest funds' heavy investments in emerging-market assets.
The Indian rupee hit a record low and Indonesia's rupiah weakened near an all-time low. The Australian dollar, a proxy for Chinese growth because of the large volume of metals Australia sells to China, hovered near its lowest in 2-1/2 years.
Copper, an industrial metal China uses heavily, lost 0.53 percent, adding to a nearly 20 percent drop already this year.
Beijing had warned of retaliation if Washington launched any new trade measures. But it is running out of room to match them dollar-for-dollar, raising concern it will resort to other measures, such as weakening the yuan or taking action against U.S. companies in China.
