Amid the day's declines, one investor said he was "a bit cautious right now."
"It appears that ... risk assets have moved ahead of fundamentals," Daryl Liew, head of portfolio management at REYL Singapore, told CNBC's "Street Signs" on Tuesday. "If you look at ... the sharp run up in equity markets year to date, it's come against a backdrop of actually slowing economic numbers."
Meanwhile, Australia's ASX 200 closed fractionally lower at 6,184.80.
On Tuesday, the release of March policy meeting minutes from the Reserve Bank of Australia showed it noted that trade tensions "remained a continued source of uncertainty for the global outlook."
"The delay in tariff increases previously scheduled for 1 March had generated some optimism that tensions could ease. However, the increases in tariffs implemented in 2018 had continued to weigh on trade between the United States and China, and there had been spillover effects on some other economies," the minutes said. China is Australia's largest trading partner, according to the latest data from its Department of Foreign Affairs and Trade.
The Australian dollar fell further to $0.7095 in the afternoon, after touching a two-week high above $0.711 yesterday, when it was boosted by a weaker dollar and a rise in iron ore prices, among other factors.
