BRUSSELS, July 30 (Xinhua) -- Euro zone's business climate indicator fell to -0.21 points in July, the lowest level since May 2005, figures of the European Commission showed on Wednesday.

    The indicator was 0.13 points in June and 0.58 points in May.

    The low level of the indicator suggests that economic activity in industry remains subdued in the euro zone, commented the commission, the executive body of the European Union (EU).

    All the five underlying components of the indicator registered a decrease. Industrial managers' production expectations and their appraisal of total order books deteriorated most. Their assessment of production trend observed in recent months and export order books also declined significantly. Their assessment of stocks of finished products worsened only slightly.

    The business climate indicator is based on a factor analysis of the euro zone's aggregate balances of five of the monthly questions in an industry survey.
