China's industrial output, investment and retail sales data are expected to show a cooling in the world's second largest economy, with fixed-asset investment, an important driver of growth, seen growing at its slowest pace in nearly 13 years between January and October.
Malaysia's stock index was up 0.1 percent, while Vietnam was 0.03 percent weaker and Indonesia's Jakarta Composite Index fell 0.3 percent by midday as uncertainty over a fuel price hike weighed on sentiment.
Philippine shares were down 0.2 percent, while shares in Thailand traded steady.
Teerada Charnyingyong, a strategist at broker Phillip Securities, said there was no market-moving news to boost sentiment for Thai stocks.
Charnyingyong said regulators were considering some curbs on overheated stocks by framing some new rules by next Wednesday.
"May be there could be more monitoring and control of the stocks with high P/E ratio," she said. – Reuters
