Japan's Nikkei has been relatively flat. Reuters

The upcoming meeting between US President Donald Trump and Chinese President Xi Jinping on Thursday (April 6) has not substantially shook up Asian markets, which have remained relatively flat at midday trading hours.

Trump's anti-Chinese sentiments, a key rhetoric of his campaign trail, may be put to the test and the true picture of US-China trading relationship is expected to become clearer as both leaders meet.

Gary Burton, market analyst at IG Melbourne, also reflected a positive sentiment, "Past presidential meetings have political leaders coming away with a positive view of relationships going forward. The same could be expected at the meeting with China's president Xi Jinping later this week with President Trump at Mar-a-Lago golf club in Florida."
