Leaders of a group of developing Muslim nations began arriving Monday at Malaysia's capital Kuala Lumpur ahead of the Group of Eight developing Islamic countries, or the D8, summit, reported dpa.
Iranian President Mahmoud Ahmedinijad and Pakistani Prime Minister Yousuf Raza Gilani were the first heads of states to arrive early Monday.
Indonesian President Susilo Bambang Yudhoyono was due to arrive later for the one-day summit which begins Tuesday morning, said officials.
The D8 grouping, which also includes Bangladesh, Egypt, Nigeria and Turkey, was first formed in 1997 as a means to enhance economic cooperation between member states.
Senior officials have said while the leaders would be discussing rising oil and food prices and the impact on Muslim nations, the focus of talks would be on enhancing trade and the economic situations of member countries.
The group's leaders are expected to endorse a 10-year trade roadmap aimed at boosting economic cooperation and trade.
Malaysian Foreign Minister Rais Yatim was quoted by the official Bernama agency as saying the issue of Iran's nuclear program, and its standoff with the United States, would not be on the agenda. However, he added that leaders were free to discuss the issues separately.
