European shares closed higher on Tuesday, as the imminent threat of Western military action against Syria receded and fresh Chinese data boosted investor sentiment.
The pan-European FTSEurofirst 300 Index provisionally closed up 1.4 percent at 1,244.60 points, its highest close since May 29, with every key European bourse and industry sector posting gains. The FTSE 100 closed unofficially up 1 percent, the German DAX rallied 2.2 percent, and the French CAC closed up 1.9 percent.
Basic resources stocks were higher by 2.04 percent, after Tuesday's promising data from China for August.

Meanwhile, retail sales and fixed asset investment both came in higher than expected.

Traders also cited receding fears of an imminent strike on Syria as a reason for the gains in Europe. President Barack Obama said on Monday that he has not decided whether he will order a strike on Syria without Congressional support — and that he was uncertain he would win the vote to authorize military action in Congress.
"I'm taking this vote in Congress and what the American people are saying very seriously," Obama told NBC News.
Reports on Tuesday afternoon suggested that Syria had accepted the Russian proposal to put its chemical weapons under international control. The White House announced on Tuesday afternoon that it had agreed to talks to such a cause.
In the U.S., stocks extended their gains across the board on Tuesday, also responding positively to the news, with the Dow Jones Industrial Average jumping more than 100 pointed, lifted by Microsoft and General Electric.
