Traders took some profit after the upsurge in the Hang Seng Index on Monday, which was spurred by a tentative trade deal between China and US. While the de-escalation dispelled some gloom for global growth and boosted demand for risk assets, some economists warned of more potential clashes.
“It might be just the beginning of the inevitable collision of the two largest economies,” said Lu Ting, chief China economist at Nomura in Hong Kong. “After enjoying a rebound, markets perhaps need to ponder the medium to long-term risk. The US is still on the offensive, but China might learn much better how to dig itself in for the future attack.”
