SINGAPORE — Asia-Pacific markets were mostly lower in Wednesday trade as investors reacted to the release of China’s manufacturing activity data for September.

Mainland Chinese markets fell into negative territory in afternoon trade, with the Shanghai composite down 0.37% while the Shenzhen component shed 0.142%.

Japan markets were lower, with the Nikkei 225 shedding 1.43% while the Topix index declined 1.64%.

Hong Kong’s Hang Seng index bucked the overall trend as it advanced 0.75%. Shares of China Evergrande Group listed in the city soared more than 13% after the firm on Tuesday announced agreements with investors of its unit, Hengda Real Estate. Evergrande’s stock has seen a wave of volatility in recent days amid concerns over the firm’s financial situation.

Elsewhere, Australia’s S&P/ASX 200 dropped 1.93%. Overall, the MSCI Asia ex-Japan index was above the flatline.

Markets in South Korea are closed Wednesday for a holiday.

Meanwhile, a private manufacturing survey also showed manufacturing activity expanding in September, with the Caixin/Markit PMI coming in at 53.0. Analysts polled by Reuters expected the Caixin/Markit PMI for September to come in at 53.1 — the same level as August.

The private survey features a bigger mix of small- and medium-sized firms. In comparison, the official PMI survey typically polls a large proportion of big businesses and state-owned companies. Chinese economic data has been watched by investors for further clues on the Chinese economy’s recovery from the coronavirus pandemic.

Shares of Japanese telecommunications firms were closely watched following a recent shakeup in the sector, with Nippon Telegraph and Telephone Corporation (NTT) set to take over its telecommunications unit, NTT Docomo.

Shares of NTT fell 3.09% in Wednesday trade while NTT Docomo surged 20.82%. Meanwhile, shares of NTT Docomo’s mobile peers were lower — SoftBank Corp dipped 0.63% while KDDI shed 0.21%.

The move by NTT comes as new Japanese Prime Minister Yoshihide Suga calls on wireless carriers to reduce prices, according to Reuters, with the hope that the savings generated will stimulate consumer spending elsewhere in the economy.

The U.S. dollar index, which tracks the greenback against a basket of its peers, was at 93.942 following an earlier low of 93.792.

The Japanese yen traded at 105.51 per dollar, having seen an earlier low of 105.80 against the greenback. The Australian dollar changed hands at $0.7109 after touching an earlier high of $0.7149.
