including Morales's own political base. Following the protests, on 31 December 2010, Morales announced that the supreme decree would be annulled, saying that he was complying with his promise to "listen to the people". The protest measures were subsequently called off. Whereas Morales enjoyed consistently high approval ratings in his first term, the "Gasolinazo" was a contributory factor to a sharp decline in approval. 2011 Price crisis In the wake of the December gasolinazo, rising world food prices, and local supply disruptions (particularly around sugar), prices rose sharply in early 2011. Organizations of public transit drivers and milk producers demanded higher prices for their goods, while workers went on strike for higher wages. In early March, the government issued a Supreme Decree raising wages by 10% and the minimum wage by 20% to 815.40 Bolivianos per month, but the move failed to stop protests and strikes by the Central Obrera Boliviana labor confederation. Sanabria drug trafficking scandal A senior policymaker on narcotics policing, retired General René Sanabria, was arrested on February 24 in Panama and extradited to the United States to face narcotrafficking charges.

In the wake of the affair, Evo Morales named Colonel Ciro Farfán as new general commander of the National Police, giving him ninety days to eliminate corruption in the force. However, Farfán himself was relieved of duty on May 19 due to his involvement in a fraudulent license plate ring at the Directorate for the Prevention of Vehicle Theft (Diprove). Morales named General Jorge Renato Santiesteban Claure to replace him. Labor mobilization The Bolivian Workers' Center (COB) coordinated a 12-day general strike in April 2011. The strike covered four sectors—teachers, health workers, some miners, and La Paz municipal employees—but striker's blockades paralyzed much of the country's economic life. The strike was resolved on April 18 with a minimal addition to the government's proposed 10% nominal wage increase and a 12-point package of agreements. Indigenous protests In July 2011, following the beginning of construction on the Villa Tunari across the Isiboro (TIPNIS), the Subcentral TIPNIS (the representative institution of indigenous residents in the
