The World Energy Congress in the Italian capital runs through Thursday, drawing chief executives, researchers and government officials from dozens of countries, including the United States , Russia , China and Brazil .
With oil prices surging near US$100 ( EUR 68) per barrel, the roughly 4,000 delegates are expected to focus on improving cooperation between importers and exporters, as well as on sustainable energy and ways to reduce greenhouse gas emissions.
Oil prices have been rising amid concerns about supplies, the weak U.S. dollar and the apparent reluctance of producing countries to pump more crude into the market. Though some analysts blame market speculation for the current surge, others believe booming demand from developing countries like China and India will keep prices at historically elevated levels.
Energy tensions also rose in recent years when Europe saw energy supplies disrupted by disputes between Russia, a major energy exporter, and countries through which energy supplies pass on their way to Germany , Poland and elsewhere.
While the Rome forum formally opened Sunday evening, the main discussions were scheduled to begin on Monday with a keynote address by European Commission President Jose Manuel Barroso.

Top industry chiefs listed among the speakers include Rex Tillerson, chairman and chief executive of Exxon Mobil Corp. and Abdallah Jum'ah, president and CEO of Saudi Aramco.
