Mousa Mousavi highlighted the importance of investment in the oil industry, saying, "The parliament is determined to pass laws that streamline domestic and foreign investment in oil and energy." He noted that numerous laws supporting investment have been approved, particularly during the 11th Parliament.

Mousavi said attracting investment in oil and gas is a serious priority for the Parliament and the Energy Committee, adding that various parliamentary committees, including Energy, Industries and Mining, and Production Leap, have made extensive efforts to pass laws that ease investment in the oil industry and have effectively supported the government in this regard.

Stressing the private sector’s key role in attracting investment, he said, "Today, many new technology-based firms (NTBFs) are active in oil and gas, and their capabilities—especially in petrochemicals—should be utilized." He acknowledged that progress has been made in this area, with improved perceptions of the private sector and knowledge-based firms.

Mousavi said belief in domestic investment must be put into practice, adding, "The private sector undoubtedly has high capabilities, so oil sector officials should trust it more than before. The parliament will support this approach, with the Energy Committee leading the way."
