SHANGHAI, Jan 9 (Reuters) - China's yuan ended the domestic session at a near five-month high against the dollar on Monday, underpinned by optimism over economic recovery following the country's border reopening and seasonal demand for the local unit.

The onshore yuan finished the domestic trading session at 6.7712 per dollar, up 523 pips or 0.77% from the previous late night close of 6.8235 on Friday. It was the strongest such close since Aug. 15, 2022. (Reporting by Winni Zhou and Brenda Goh; Editing by Alex Richardson)
