Here are five things you must know for Tuesday, May 28:

1. -- Stock Futures Fall Amid Trade Uncertainties

U.S. stock futures were lower on Tuesday as Wall Street returned from the three-day Memorial Day weekend and caution still prevailed amid concerns over the fate of trade talks between Washington and Beijing.

Contracts tied to the Dow Jones Industrial Average fell 37 points, futures for the S&P 500 were down 7.55 points, and Nasdaq futures declined 17.25 points.

Donald Trump wrapped up a four-day state visit to Japan on Monday with a series of comments that suggested little progress in the U.S.-China trade dispute, telling reporters during a press conference with Japanese Prime Minister Shinzo Abe that he's "not ready to make a deal" with Beijing.

"I think sometime in the future China and the United States will absolutely have a great trade deal, and we look forward to that," the president said, before repeating his incorrect assertion that China was responsible for paying tariffs on goods imported into the United States. "Because I don't believe that China can continue to pay these, really, hundreds of billions of dollars in tariffs. I don't believe they can do that."

Despite threats from Trump of new and "very, very substantial" levies on China imports, Chinese and Asian stocks finished with solid gains Tuesday. European markets traded lower as the weekend's European parliamentary elections showed solid gains for pro-EU parties.

The economic calendar in the U.S. Tuesday includes the S&P Corelogic Case-Shiller Home Price Index for March at 9 a.m. ET, and Consumer Confidence for May at 10 a.m.

Earnings reports are expected Tuesday from YY Inc. (YY - Get Report) , Nio Inc. (NIO)  and Momo (MOMO - Get Report)  .

2. -- France Wants Jobs Protected in Fiat Chrysler-Renault Merger

Shares of Italian-American carmaker Fiat Chrysler Automobiles (FCAU - Get Report)   and France's Renault rose Tuesday after Fiat Chrysler proposed the companies merge in a deal that would create the world's third-biggest automaker.

The French government said it needed jobs protected and board seat guarantees in order to support the proposed $35 billion merger of the two carmakers.

France's finance minister, Bruno le Maire, said the government asked for "four guarantees" before it would back the proposal, which would create a 50-50 ownership structure while reducing the French government's stake to 7.5%.

"The first: industrial jobs and industrial sites. I told Renault Chairman Jean-Dominique Senard very clearly that it was the first of the guarantees I wanted from him in the opening of these negotiations with Fiat," le Maire said. "A guarantee on the preservation of industrial jobs and sites in France."

A merger of Fiat Chrysler and Renault would create an automaker capable of making 8.7 million cars a year, putting it in third place behind Germany's Volkswagen  (VLKAY) and Japan's Toyota  (TM - Get Report) .

Under the deal, Renault could find entry into the U.S. while at the same time extracting itself from its now-combative tie-up with Japan's Nissan (NSANY) following the arrest of former CEO Carlos Ghosn last year in Tokyo amid allegations of financial misconduct.

3. -- Alibaba Mulls Raising $20 Billion Through Hong Kong Listing

Alibaba (BABA - Get Report) , the Chinese e-commerce giant, is considering raising $20 billion through a second listing in Hong Kong, according to Bloomberg, which cited people with knowledge of the matter.

Alibaba currently is working with financial advisers for the potential offering.

A confidential listing could happen by later this year, said the report, and Alibaba has said on background it wouldn't rule out another listing in an effort to diversify its business.

A massive online presence, Alibaba's fiscal 2019 full-year revenue was $56 billion. In fiscal, Alibaba expects revenue of about $72.5 billion.


4. -- Teva to Pay Oklahoma $85 Million in Opioid Lawsuit

Israeli drugmaker Teva Pharmaceutical (TEVA - Get Report) reached an agreement with Oklahoma that includes an $85 million payment to the state, ahead of a trial slated for Tuesday over opioid claims.

"The company has resolved this matter in a way that benefits the people who have suffered from abuse of opioids and to help stop the effects of the opioid crisis. Teva continues to keep the long-term stability of the company at the forefront," Teva said.
