HONG KONG, May 2 (Reuters) - Hong Kong and China shares started May on a weaker footing on Thursday as soft China manufacturing data put growth-sensitive counters on the defensive as mainland markets returned from a three-day public holiday.
The final China HSBC Purchasing Managers' Index (PMI), released on Thursday, dropped to 50.4 in April from March's 51.6 and was largely in line with a flash reading last week of 50.5.
China's official PMI on Wednesday fell to 50.6 in April from an 11-month high of 50.9 in March.
By midday on Thursday, the Hang Seng Index was down 0.3 percent at 22,669.8 points, pulling away from Tuesday's seven-week closing high. The China Enterprises Index of the leading Chinese listings fell 0.9 percent.
The CSI300 of the leading Shanghai and Shenzhen A-share listings was flat, while the Shanghai Composite Index slipped 0.2 percent. They are down 3 and 4.2 percent on the year, respectively.
Markets in Hong Kong were also shut on Wednesday for the Labour Day public holiday.
"A-share volumes are still very weak. For retail investors, it's hard to justify putting their money in stocks right now with data looking weak and Beijing not looking like it will loosen policy too much," said Zhang Qi, a Shanghai-based analyst with Haitong Securities.
On Thursday, Jiangxi Copper dived 2.8 percent in Shanghai and 1.1 percent in Hong Kong after Shanghai copper prices fell nearly 5 percent in early trade as Chinese markets resumed trading for the first time this week.
Lenovo Group tumbled 3.4 percent, heading for its worst day in three weeks, after Fortune magazine reported that the Chinese personal computer maker and IBM have called off negotiations over a multibillion-dollar deal for Big Blue's low-end server business.
Premium alcohol producers were also hit by a fresh warning on Wednesday that some government officials were avoiding new President Xi Jinping's graft-busting instructions to be frugal by taking banquets and other lavish displays underground, including hiding liquor in water bottles.
Kweichow Moutai fell 1.4 percent in Shanghai, while Wuliangye fell 2.1 percent in Shenzhen.

In Hong Kong, China Overseas Land rose 1.1 percent, while China Resources Land gained 0.6 percent to near a three-month high.
