BANGALORE/SYDNEY (Reuters) – Factory activity in Europe and Asia cooled in August after a strong July, as new orders dwindled in the face of escalating tensions in Ukraine and a patchy recovery in China, purchasing managers indexes showed. Despite euro zone manufacturers barely raising their prices, growth in the region slowed slightly more than initially thought, and activity in China’s vast factory sector slackened on weak foreign and domestic demand, stoking speculation that further policy stimulus would be needed.
