MSCI's broadest index of Asia-Pacific shares outside Japan was up 0.5 per cent after Trump's upbeat tone in comments on Thursday, despite a lack of agreement between Washington and Beijing over whether existing tariffs should be dropped as part of a preliminary trade deal.
On Thursday, the Sensex and Nifty indices settled on a weak note after Asia's most aggressive central bank - Reserve Bank of India - surprised analysts and economists by pausing to cut repo rate at its December monetary policy review.
The Reserve Bank of India (RBI) kept the benchmark interest rate unchanged at 5.15 per cent and reverse repo rate at 4.90 per cent on concerns of headline inflation breaching its medium-term target.
However, the RBI promised to continue with its accommodative stance in its monetary policy.
