"For the Bank of Japan and for policymakers, the message is very, very clear: the industrial part of the Japanese economy is in recession," Jesper Koll, senior adviser at WisdomTree Investments, told CNBC's "Squawk Box" on Wednesday.
That jump in U.S. markets came after U.S. President Donald Trump said in a tweet he "had a very good telephone conversation " with Chinese President Xi Jinping. He added: "We will be having an extended meeting next week at the G-20 in Japan. Our respective teams will begin talks prior to our meeting." The summit will start on June 28.
The offshore Chinese yuan saw strong gains against the greenback following Trump's comments, it last traded at 6.9067 after seeing levels above 6.93 yesterday, while its onshore counterpart changed hands at 6.9047.
Still, one economist voiced doubt about the upcoming meeting.
"We do not believe that the meeting will deliver a trade deal, even if the meeting does take place. From the Chinese side, the discussion with US President Trump is expected only to exchange views on fundamental issues concerning the development of China-US relations," Iris Pang, Greater China economist at ING, wrote in a note.
"The news on the talks in Osaka is a short term positive for asset markets, but we believe any talks will change little unless either side makes some meaningful concessions, which we do not view as likely at this time," Pang said.
Trade tensions between the two economic powerhouses had worsened in recent weeks with both raising tariffs on billions of dollars worth of their goods. Trump had also previously suggested that additional levies could be imposed on more Chinese imports.
Meanwhile, the U.S. Federal Reserve kicked off a two-day monetary policy meeting on Tuesday. The Fed is widely expected to leave interest rates unchanged at this meeting, though investors will be watching out for hints on rate cuts later in the year.
Expectations for a rate cut have increased in recent weeks, amid data on slowing jobs growth and manufacturing activity, as well as concerns over the impact of Washington's protracted trade fight with Beijing on the global economy.
Meanwhile, Mario Draghi, president of the European Central Bank, indicated there could be more stimulus measures in Europe. He said Tuesday: "In the absence of improvement, such that the sustained return of inflation to our aim is threatened, additional stimulus will be required."
Trump criticized Draghi's remarks, noting additional ECB stimulus makes it "unfairly easier" for Europe to compete with the U.S. For his part, Draghi responded by saying "we don't target the exchange rate."
The euro last traded at $1.1196, following a slide yesterday from levels above $1.123.
