Euro zone manufacturing growth slowed slightly more than initially thought last month as new orders dwindled and factories suffered amid rising tensions in Ukraine, a business survey showed on Monday. Factories barely increased prices last month, and manufacturing activity in France fell at the fastest pace in 15 months, in disappointing news for the European Central Bank before Thursday’s monetary policy-setting meeting. Markit’s final August manufacturing Purchasing Managers’ Index came in at 50.7, the lowest in over a year and below both July’s 51.8 and an earlier flash estimate of 50.8.
