MANILA, Nov 9 (Reuters) - The Philippine economy lost some growth momentum in the third quarter after a stronger-than-expected performance in the previous three months, due to renewed COVID-19 restrictions, the statistics agency said on Tuesday. Gross domestic product rose 7.1% in the September quarter from a year earlier, slower than the upwardly revised 12.0% expansion in the previous quarter, but above the 4.8% forecast in a Reuters poll.
