The UN chief told a press briefing in Sri Lanka's capital of Colombo that the cash aid will be important for the battered areas during the next six months.

"We must reassure them (the world donors) that the money will be used properly and effectively," Annan said.

He, starting the tour in Sri Lanka on Friday, also pledged the UN support for the country's reconstruction process.

The World Bank (WB) President James D. Wolfensohn told reporters Saturday night in Colombo that the bank will support theSri Lankan government in "a fast, transparent and effective way" to assist the tsunami-hit communities to rebuild their homes.

"WB will support the Government as it develops a fast, transparent and effective way to convert the billions of dollars pledged all over the world into the rupee in the hands of the poorfisherman in Sri Lanka to repair his boat or for a community to rebuild its homes," Wolfensohn said.

The bank has reserved about 100 million US dollars for post-Tsunami rebuilding in Sri Lanka from existing projects.

In addition, an emergency credit of not less than 75 million dollars will be made to enable the government to begin recovery work.
