OSLO (AFP) - Norway will provide 800 million kroner (100 million euros, 134 million dollars) in aid to Haiti over the next four years, the foreign ministry said Wednesday, adding to an earlier pledge.

"Following the earthquake that hit Haiti on January 12, Norway has given 200 million kroner in emergency aid. Now Norway wants to strengthen its longterm aid, increasing its contribution by 600 million kroner," the ministry said.

Norwegian state secretary Ingrid Fiskaa would present Norway's new pledge at a United Nations fund-raiser in New York Wednesday for the battered Caribbean island nation, it said in a statement.

"The earthquake has led to great suffering for Haitians. More than one million people have no place to live. But if we are to help Haiti, we must do more than build houses," Fiskaa, who was due to address the conference, said in the statement.

"We must help the Haitians to build a completely new society," she said, adding all citizens should have the possibility of influencing their political system and the opportunity to rise out of poverty.

Some 138 countries, international bodies such as the World Bank and the International Monetary Fund, non-governmental organisations and representatives of the Haitian diaspora were set to attend the conference, aimed at raising around 3.8 billion dollars for Haiti for the next 18 months.

Haiti, already the poorest country in the Americas before the quake, was devastated by the earthquake, which leveled parts of its capital Port-au-Prince and killed at least 220,000 people, leaving 1.3 million homeless.
