South Korea's economy posted improved growth in the second quarter on increased exports and consumption, central bank data showed Tuesday. 
In the three months that ended June 30, the country's gross domestic product (GDP) grew 0.7% from a quarter earlier, according to preliminary data from the Bank of Korea (BOK). 
The second-quarter estimate marks an improvement from a 0.5% on-quarter expansion in the previous quarter. From a year earlier, it marks a 3.2% improvement. 
Domestic consumption inched up 0.7% from three months earlier as government spending grew 0.2%, and private expenditures went up 0.9%, according to South Korea's (Yonhap) News Agency. 
Exports, a major pillar of growth for Asia's fourth-largest economy, grew 0.9% from the previous quarter. 
Gross domestic income, on the other hand, fell 0.4% from the previous quarter, worsening from a 3.0% rise three months earlier, the BOK said.
