HAMBURG (Reuters) - TCP has issued another international tender to purchase 50,000 tonnes of white sugar, European traders said on Monday. The move means Pakistan is seeking to purchase a total of 450,000 tonnes of sugar in world markets. The latest tender from any origin worldwide closes on Feb. 22 and continues a surge of purchase interest from the country. The TCP has in the past week issued 2 other separate tenders for 50,000 tonnes each, closing on Feb. 15 and Feb. 20. The TCP has in the past month issued tenders to import 150,000 tonnes of white sugar, one of which will close on Feb. 13. Another tender for 150,000 tonnes will close on Feb. 6. Pakistan is among several Asian countries struggling to meet sugar needs in the face of soaring prices. Sugar futures are hovering within sight of a 29-year-high reached in early January and have more than doubled last year. The government has decided to import about 500,000 tonnes of white sugar through the TCP which is expected to be purchased by March 31, officials said. Pakistan on Jan. 13 also announced plans to allow the duty-free import of 700,000 tonnes of sugar to encourage imports by the private sector to take the heat off domestic sugar prices. Other Asian buyers with large requirements include the Philippines, which will need to import 150,000 tonnes this year, its first purchases since it became a net export in 2003, while Indonesia has held a series of tenders to cover a supply shortfall.
