Asian shares pushed higher on Friday after US President Joe Biden signed a $1.9 trillion stimulus bill into law, and as a retreat in bond yields overnight eased global concerns about rising inflation.
Mr Biden signed the legislation ahead of a televised address in which he pledged aggressive action to speed vaccinations and move the country closer to normality by July 4.
