South Korea's export prices rose for the sixth straight month in May amid a recovery in exports. 

According to data from the Bank of Korea(BOK) on Friday, the country's export price index, in terms of the local currency, gained one-point-five percent on-month in May. 

From a year earlier, the index jumped 12-point-three percent, marking the largest on-year gain since March 2009. 

Meanwhile, the country's import price index rose two-point-six percent on-month in May. From a year earlier, the index soared 13-point-eight percent. 

The rise is attributed to price increases of imported products converted to the local currency due to rising prices of oil and raw materials.
