According to traders, investors took cues for other Asian bourses which were trading higher after U.S. President Trump hinted at the possibility of a trade deal with China, in a series of tweets.

“When the time is right we will make a deal with China... Respect and friendship with President Xi is unlimited,” he wrote.

“We can make a deal with China tomorrow, before their companies start leaving so as not to lose USA business” he added.

Sustained foreign fund outflow, however, weighed on investor sentiment here, capping the gains on key bourses, traders said.
