SEOUL, Sept 1 (Reuters) - South Korea's factory sector recorded a ninth consecutive month ‌of activity growth in August, underpinned ‌by robust export demand, a survey showed on Tuesday.

• ​The purchasing managers index (PMI), published by S&P Global, stood at 52.3 in August, down from 53.1 in July, but staying above the ‌50 mark separating ⁠expansion from contraction for a ninth consecutive month.

• Manufacturers continued to ⁠report healthy new orders with a sub-index measuring new orders at 53.5 in August compared ​with 54.8 ​in July, according ​to the survey.

• "While ‌August PMI data signaled an easing of overall new order growth across South Korean manufacturers, a robust increase in export demand – the strongest recorded since November 2020 – is an ‌encouraging sign that firms ​are still benefitting from the ​current AI ​and semiconductor supercycle," said David Owen, ‌an economist at S&P ​Global Market ​Intelligence.

• Asia's fourth-largest economy grew faster than expected in the second quarter, driven ​by a ‌semiconductor export boom that offset a decline ​in construction investment.
