On the trade front, the Trump administration intends to offer as much as $12 billion in aid to support farmers affected by tariffs in ongoing disputes between the U.S. and its trading partners.
U.S. tariffs on $34 billion in Chinese imports took effect earlier this month and were met with retaliatory measures from Beijing that targeted the same value of U.S. goods, including American soybeans among other products.
U.S. President Donald Trump said in a Twitter post earlier on Tuesday that "Tariffs are the greatest! Either a country which has treated the United States unfairly on Trade negotiates a fair deal, or it gets hit with Tariffs. It’s as simple as that - and everybody’s talking!"
That came ahead of his meeting with European Commission President Jean-Claude Juncker on Wednesday U.S. time, with talks expected to be focused on American tariffs on steel and aluminum and other trade-related issues.
In currencies, the dollar index, which tracks the U.S. currency against a basket of peers, slipped slightly to 94.486 while the euro was just a touch firmer at $1.1694 in the lead up to the meeting.
Against the yen, the dollar was mostly steady at 111.17 at 3:05 p.m. HK/SIN.
The mixed session in Asia also came on the back of U.S. stocks mostly rising overnight on the release of strong corporate earnings, with Google-parent Alphabet jumping 3.9 percent after the company reported expectations-topping results after the market close on Monday.
Among individual movers, LG Display fell 4.66 percent after the company said it expected the LCD industry to go through "restructuring," Reuters said. The manufacturer had earlier gained after reporting a smaller-than-expected loss of 228 billion won ($202.2 million) in the morning.
Meanwhile, SK Engineering and Construction shareholder companies saw their stocks drop after a dam the construction company was building in Laos collapsed. Hundreds of people are currently missing in the wake of the accident, Reuters reported. SK Holdings dropped 5.11 percent and SK Discovery lost 11.89 percent.
Elsewhere, shares of Changsheng Bio-technology were halted from trade on Wednesday, with the suspension expected to lift on Thursday, according to Reuters. The pharmaceuticals company has seen its stock plunge amid a vaccine scandal happening in China over safety standards violations.
