SHANGHAI, Oct 8 (Reuters) - Shares in Asia staggered on Monday as China's markets stumbled despite its central bank moving to pump more liquidity into the broader economy, as worries grow of a sharp knock to growth from an escalating trade dispute with the United States.

The tech-heavy ChiNext board .CHINEXTP fell 2.9 percent.
"We expect the PBoC will continue its easing efforts to keep liquidity ample and loosen its credit control to make funds more accessible to the broader economy," BofA Merrill Lynch analysts said in a note.
"Moreover, there is still room for further RRR cuts when necessary, though the chance for an interest rate cut is limited given the continued Fed rate hiking cycle, in our view."
