TOKYO — The bitter trade war between China and the United States kept Asian factory activity mostly in decline in August, business surveys showed, strengthening the case for policy makers to unleash fresh stimulus to fend off recession risks.

In a surprise development, China’s factory activity unexpectedly expanded in August as output edged up, a private sector purchasing managers’ index (PMI) showed on Monday, but orders remained weak and business confidence faltered.

Export-reliant South Korea, Japan and Taiwan also saw factory activity shrink, underscoring the growing pain from the tit-for-tat tariff war between the world’s two-largest economies.

“The broader picture for Asian exports remains very weak because of the impact of the US-China trade war, which is continuing to escalate,” said Rajiv Biswas, Asia Pacific chief economist at IHS Markit.

In a fresh escalation of trade tensions, the United States began imposing 15% tariffs on a variety of Chinese goods on Sunday. China reciprocated with new duties on US crude oil.

In China, the Caixin/Markit Manufacturing Purchasing Managers’ Index (PMI) for August rose to a five-month high of 50.4 from 49.9 in July, beating a median market forecast and exceeding the 50-point level that separates contraction from growth on a monthly basis. The reading followed Beijing’s official PMI that showed factory activity shrank in August for the fourth month in a row, pointing to a further slowdown in the world’s second-largest economy.

India, another Asian economic power-house, saw the slowest expansion in its manufacturing sector in 15 months as demand and output grew at their weakest pace in a year. Data on Friday showed India’s economic growth hit a 6-year low in April-June, raising chances of the central bank cutting interest rates further at its next meeting.

Elsewhere in Asia, Japanese manufacturing activity fell for a fourth straight month in August, underlining a darkening outlook for the world’s third-largest economy. While Japan’s exports slipped for an eighth month in July due to slumping China-bound sales, the economy has so far enjoyed steady growth thanks to robust domestic demand.

But there are signs the economy may start to lose the support from consumption and capital expenditure. Manufacturers surveyed in the PMI data said the end of a construction spike ahead of the 2020 Tokyo Olympic Games and a scheduled sales tax hike in October are expected to hurt output volumes the coming months.

Any further sign of weakness in domestic demand could add pressure on the Bank of Japan to ramp up stimulus at its rate review on Sept. 18-19, which follows the European Central Bank’s rate decision and that of the US Federal Reserve.

“The US-China trade war is escalating and we’re also seeing tensions heighten between Washington and Europe,” which could cause the global economy to falter, said Yoshimasa Maruyama, chief market economist at SMBC Nikko Securities.

“Japan may slide into recession around the time the sales tax hike takes effect.”

South Korean’s factory activity also shrank as manufacturers felt the pinch not just from the US-China trade war but an escalating diplomatic dispute with Japan.

The country’s exports tumbled in August for a ninth straight month on sluggish demand from its biggest buyer, China, and depressed prices of computer chips globally.

The bleak data strengthened the case for additional policy easing by South Korea’s central bank, following a surprise interest rate cut in July.

“The simple message is number one, the US and China are at logger heads, and China is already proactively responding and basically started to divorce itself from the regional supply chain,” said Michael Every, senior Asia-Pacific strategist at Rabobank.

“Eventually the service sector will be dragged down by the manufacturing sector.” — Reuters
