Nov 28 (Reuters) - Australian shares edged lower on Wednesday as Sino-U.S. trade uncertainty ahead of talks between the leaders of the two countries and an overnight fall in commodity prices weighed on sentiment.
Investors were wary of buying into riskier assets amid conflicting comments from White House economic adviser Larry Kudlow and U.S. President Donald Trump on the likelihood of a thaw in the Sino-U.S. trade dispute.
Trump and his Chinese counterpart Xi Jinping are due to hold talks, centring on the contentious trade issues, on the sidelines of a G20 gathering in Argentina at the weekend.

Iron ore futures in China firmed on Wednesday after expectations of slower demand pushed prices to their lowest level in four-and-a-half months in the previous session.
