HONG KONG, March 6 (Reuters) - Hong Kong stocks rebounded on Wednesday from a decline in the previous session while China shares were largely flat as investors await policy support details from the National People's Congress (NPC) this week.

** Hong Kong's Hang Seng Index climbed 1.7%, and the Hang Seng China Enterprises Index jumped 2%.

** The blue-chip CSI 300 Index dipped 0.4%, and the Shanghai Composite Index edged down 0.3%, both snapping a four-day winning streak.

** Chinese Premier Li Qiang announced an ambitious 2024 economic growth target of around 5% on Tuesday in his maiden work report. However, investors and analysts remain cautious as the report lacks policy details that support the achievement of the target.

** "We think risk sentiment may remain volatile in the coming days as investors process the fiscal pledges and wait for industry-specific policies," UBS Global Wealth Management's chief investment office said in a note.

** Morgan Stanley economists pointed out that the fiscal package, which set the fiscal deficit target at 3% of GDP, remains insufficient to boost the economy amid mounting local government debt pressure.

** The economic rebalancing efforts remain relatively slow, they added.

** Meanwhile, investors are closely monitoring a press conference on Wednesday, which is being attended by top policymakers.

** "We will further strengthen the protection of investors... to attract more investment, especially long-term funds to participate in this market," Wu Qing, the newly-appointed chairman of the China Securities Regulatory Commission (CSRC),

told

reporters.
