Southeast Asian stocks fell on Wednesday while Singaporean and Malaysian shares sank after disappointing economic data from China.
However, a rally in real estate stocks drove Philippine and Vietnamese equities higher, reports Reuters.
Other Asian markets also fell after a private survey showed that China's factory activity had contracted for the first time in 19 months in December as domestic and export orders continued to weaken.
The news is the latest in a slew of worrying economic data from Southeast Asia's biggest trading partner, reinforcing fears that China's economy is losing more steam amid a bitter trade war with the United States.

Malaysian equities also dropped sharply, with a 2.3 per cent slide each in Sime Darby Plantation Bhd and gas retailer Petronas Dagangan Bhd pulling the benchmark down 0.86 per cent.
