China's indexes advanced in cautious trading as investors reviewed the latest updates on key economic indicators. 

The Hang Seng Index decreased 0.6%, and the mainland-focused CSI 300 Index declined 0.9%, with markets turning choppy after recent gains in technology and semiconductor stocks. 

Semiconductor stocks led the overall market rebound in the previous two weeks amid strong earnings and Beijing's continued support to develop a self-sufficient industry. 

Investor sentiment was cautious after the release of July's industrial production, retail sales, fixed-asset investment, and jobless rate, and industrial production data. 

New home prices in China's top-tier four cities decline in July from a year ago amid persistent demand weakness. 

Prices fell 2.3% in Beijing, decreased 2.2%, and in Shenzhen eased 2.9%, but rose in Shanghai by 3%, according to the National Bureau of Statistics. 

Property investment downturn intensified and fell in the first seven months to 19.2% from an 18% decline in the first six months to June. 

Sales of new homes by floor area declined 11.8% in the first seven months, following an 11.6% decline in the first half of the year.   

China's persistent property market weakness has weighed on the broader economy for five years, but the sector has gained traction in recent months on the back of supportive measures from the People's Bank of China and local regulators. 

Geopolitical tensions remained high after the U.S. and Iran ended a two-month ceasefire on Monday, and the Brent crude oil price increased 0.6% to $91.45 a barrel.  

The energy product shipment through the Strait of Hormuz is likely to remain disrupted for a prolonged time amid fading hopes for a Middle East peace deal.
