MILAN/LONDON, Oct 13 (Reuters) - European shares fell on Tuesday following disappointing Chinese import data, dragged down by auto and mining stocks, though SABMiller soared after accepting a takeover proposal from rival Anheuser-Busch InBev.
The pan-European FTSEurofirst 300 index was down 1.3 percent, with the euro zone's blue-chip Euro STOXX 50 also down 1.3 percent.
China's exports fell less than expected in September, but a sharper fall in imports left economists divided over whether the world's second largest economy's ailing trade sector is showing signs of turning around.
"While Chinese exports posted a healthy rebound, weak imports are still indicating that the Chinese economy is continuing to struggle," said Markus Huber, trader and analyst at Peregrine & Black.
Cars and miners were among the top sectoral fallers following the data. But Huber said some investors viewed the data as a catalyst for more Chinese government and central bank action in the coming months, adding that the lower prices could tempt buyers back into the market.
The uncertain mood was reinforced by a survey by ZEW think tank that showed morale among German analysts and investors plummeted in October to its lowest level in a year.
SABMiller rose 9.3 percent after it accepted an offer worth more than $100 billion from AB InBev, which rose 1.3 percent. SABMiller said it had indicated to AB InBev that its board would be prepared to accept the offer.
"AB InBev's fifth bid ... marks a firm step towards the biggest deal of the year and reflects the larger brewer's conviction regarding the logic of a tie-up which would open unparalleled access to new markets," said Jonathan Buxton, partner and head of consumer at Cavendish Corporate Finance.
Shares in Germany's two biggest utilities, E.ON and RWE were the top fallers on Germany's DAX , with traders pointing to profit taking following strong gains a day earlier.
In the banking sector, Credit Suisse and UBS both fell around 1.4 percent after a report said the Swiss finance ministry would tighten capital requirements.
Portuguese banks were sharply lower for a second day, dragged down by political uncertainty over the new government after last week's inconclusive elections.
Banco Comercial fell 5.3 percent and Banco BPI was down 3.6 percent.
"The fall is very much linked to the possibility of having a leftist government," Luis Castro, a trader at Golden Broker in Porto, said.
SAP was 5.1 percent higher after Europe's biggest software maker reported a 19 percent rise in third-quarter operating profit, beating the most optimistic analyst estimate.
LVMH fell 3.1 percent after the luxury goods industry leader reported a mixed set of third-quarter revenue figures that revealed a strong rebound in cognac sales, particularly in China, but a slowdown at its fashion and leather business.
German-listed Leoni fell 34 percent, the top STOXX Europe 600 faller, after warning on 2015 and 2016 profit, citing problems at its Wiring Systems business. ($1 = 0.6551 pounds) (Additional reporting by Patricia Rua in Lisbon; Editing by Tom Heneghan)
