The right to regulate seeks to balance investor’s economic interests in investment protection with host states’ interests in pursuing public policy objectives such as environmental protection and human rights (distributive justice). Achieving this delicate balance, however, is quite tricky. Whilst these reforms elevated the right to regulate to new lights, they equally exposed Tanzania to new investment arbitration claims. This article has reviewed related literature, statutes and case laws and observed that regulatory measures taken in pursuance of these reforms may be at odds with investment treaty standards and commitments entered by Tanzania in investment treaties. The article reveals that majority of bilateral investment treaties entered by Tanzania do not contain provisions recognizing or implicating right of states to regulate. In essence, this contradicts legal reforms done in 2017. It is, therefore, recommended that Tanzania should review investment treaties so that they also reflect the right of states to regulate. By complementing efforts done under domestic investment laws, this will help to safeguard the right of state to regulate.enRight-RegulateNatural Wealth and ResourcesTanzaniaChallengeProspectsArticle
