Shares in China have slumped as details of economic stimulus plans from officials in Beijing failed to meet investors' expectations, while other markets in Asia are higher.

Traders are closely watching for additional policy measures as Beijing has signaled a sense of urgency in bringing its economy back on track.

China's stock markets roared back from a week-long break to reach their highest levels in more than two years at the open, before paring gains after officials failed to inspire confidence in stimulus plans intended to revive the economy.
