President Donald Trump and China's president, Xi Jinping, are set to meet next week in Japan at the G-20 summit, where they're expected to reengage in trade talks. But if the world's two largest economies fail to make a deal, investors should brace for a possible further economic slowdown and potentially more retaliatory tariffs.
"We can't afford to let it drag on too long," Cashin said in an interview on "Squawk Alley." "First of all, the president can't afford it because of the election coming up."
"Obviously, if you're running for office, you don't want that," Cashin added.
Nuclear talks between the Trump administration and North Korea reached a stalemate in February after the two sides failed to agree on the removal of sanctions.
The Chinese could potentially strike a deal with North Korea that benefits the U.S., and ask the White House to back off on some of its trade demands, Cashin said.
