SYDNEY -- Asian share markets got off to a sluggish start on Tuesday amid uncertainty over both the Sino-US trade talks and the domestic political situation in Hong Kong.

Caution ruled ahead of a speech by US President Donald Trump to the Economic Club of New York later in the day in case there was any new word on the Sino-US Phase one trade deal.

On a more positive note, Politico reported Trump would announce this week that he is delaying a decision on whether to slap tariffs on imported European Union autos for another six months.
Investors were also eyeing the situation in Hong Kong after a violent escalation of protests knocked nearly 2 percent off Asia-exposed banks HSBC and StanChart.
