Investors' focus has now shifted to a meeting between US President Donald Trump and China's President Xi Jinping during a Group of 20 summit in Japan next week, with hopes that they can put negotiations back on track to de-escalate a trade war. Trump said that he would decide whether to carry out his threat to hit Beijing with tariffs on at least $300 billion in Chinese goods after the meeting.

Investors have pinned hopes on some sort of compromise emerging when U.S. President Donald Trump meets China's President Xi Jinping on the sidelines of the G20 summit in Japan on June 28-29.

Meanwhile, fears of a military confrontation in the Middle East Gulf were raised after Iran shot down a U.S. military drone. Iran's Revolutionary Guard said it shot down a U.S. drone over Iranian airspace. U.S. officials said the drone had not violated Iranian airspace. The drone shooting follows an attack last week on two oil tankers near the Gulf of Oman. The New York Times reported that U.S. President Donald Trump had approved military strikes on Friday against Iran in retaliation, but pulled back from launching the attacks.

Also late Thursday, the Federal Aviation Administration prohibited U.S. carriers from flying over Iranian-controlled parts of the Persian Gulf and Gulf of Oman, over fears of a jetliner accidentally being shot down.
