Equinor, one of the companies involved in the talks, could be selected for the project, according to the Energy Ministry.
The construction of the LNG export terminal near huge offshore natural gas discoveries in deep water, south of the country, has been held up for years by regulatory delays.
Negotiations between the government and international oil companies, which started in 2017, have so far failed to lead to a deal. The project is meant to enable the export of gas from Tanzania.
The new round of talks will ensure all parties involved will benefit fairly from the project, Energy Minister Medard Kalemani said at a meeting with Equinor executives.
Equinor, alongside Royal Dutch Shell, Exxon Mobil and Ophir Energy, plan to build a $30 billion onshore LNG plant.
“we are keen to implement this key project for the economy by concluding the talks in September this year,” the ministry said.
Tanzania has an estimated 58 trillion cu ft of natural gas reserves. President John Magufuli said he would pursue partnerships that enable his nation to benefit more from its resources.
