Congo and the United States ratified a bilateral investment treaty designed to facilitate and protect foreign investment. The country also adopted a new investment code intended to attract foreign capital. Despite this, Congo's investment climate is not considered favorable, offering few meaningful incentives. High costs for labor, energy, raw materials, and transportation; a restrictive labor code; low productivity and high production costs; militant labor unions; and an inadequate transportation infrastructure are among the factors discouraging investment. The recent political instability, war damage, and looting also undermined investor confidence. As a result, Congo has little American investment outside of the oil sector.
