China's Premier Li Keqiang, on a tour of South America, is plugging a transcontinental railway project that would cut through the heart of the Amazon rainforest. Last year, President Xi Jinping signed a memorandum on the project with the governments of Brazil and Peru, and Li is now pressing for an actual feasibility study. According to an interactive map on Diálogo Chino website, the "Twin Ocean Railroad" or "Transcontinental Railroad" would start at Porto do Açu in Rio de Janeiro state, and cut through the Brazilian states of Goiás, Mato Grosso and Rondônia. It would terminate at Puerto Ilo in Peru's southern Moquegua region.

DEA agents in Colombia held sex parties with prostitutes hired by narco-traffickers, according to an investigation by the US Justice Department released March 26. In a series of interviews with DoJ's Office of the Inspector General, former Colombian police officers said that they arranged the parties at government-leased quarters between 2005 and 2008, and also provided protection for the agents' weapons and property during the affairs. The report goes on to detail how several DEA agents were provided money, gifts, and weapons by local drug cartel operatives.

Authorities in Colombia are carrying out their biggest manhunt since the campaign that brought down the legendary Pablo Escobar in 1993. Dario Antonio Usuga AKA "Otoniel" is leader of the Urabeños, a blood-drenched paramilitary network which is said to control much of the cocaine trade in Colombia's northern region of Urabá. The hunt, dubbed the "Siege of Urabá," has mobilized over 2,000 soldiers and National Police troops to the jungles and peasant villages of the northern region. Under a new reward just announced by President Juan Manuel Santos, Otoniel now has a $580,000 price on his head, while his associates "El Galivan," "Nicolas" and "Guagua" each have a price of nearly $200,000.

The International Agency for Research on Cancer, an arm of the World Health Organization (WHO), on March 24 officially reclassified the herbicide glyphosate as a cancer threat—citing what it called convincing evidence the chemical produces cancer in lab animals and more limited findings that it may cause a form of lymphoma in humans. Monsanto markets glyphosate as Roundup for use in agriculture worldwide, but the reclassification is especially big news in Colombia—where the government has sprayed more than 4 million acres of land in the past two decades to eradicate coca plantations.

Colombians made history March 8, as tens of thousands took to the streets in cities and towns nationwide—joined by Colombian ex-pats and immigrants in the US, Canada, Europe and elsewhere—to show their support for peace talks between the government and FARC guerillas. The "March for Life" was organized by Bogotá’s ex-mayor Antanas Mockus and was embraced by President Juan Manuel Santos, who joined the march in the capital. Since then, there have been some encouraging signs that the country's multi-decade armed conflict is really coming to an end. (EuroNews, March 9;AP, Colombia Reports, March 8)

In another case of Colombian villagers staging a local uprising in response to militarization of their communities, on March 24 a detachment of some 20 special anti-narcotics agents of the National Police were detained by indigenous peasants at the hamlet of Alto Naya, in the southern region of Cauca. Villagers apparently accused the troops, who were on a coca eradication mission, of entering indigenous lands without community consent. But the local National Police commander said consent had been secured at a meeting with village leaders held in the nearby town of Santander de Quilichao. In any event, police seemingly agreed to call off the eradication mission in order to win the release of the detained troops.

Colombia's supreme court on Feb. 27 convicted two close aides of former president Alvaro Uribe for illegal eavesdropping on the communications of the conservative leader's top opponents. Maria del Pilar Hurtado, former head of the now-disbanded DAS intelligence agency, and Bernardo Moreno, Uribe's chief of staff, were both found guilty on several charges, including conspiracy, and each face more than 10 years in prison. The convictions were widely anticipated since a number of former DAS agents accused them of ordering wiretaps of journalists, human rights defenders, politicians and even members of the supreme court who had been critical of Uribe. President Juan Manuel Santos ordered the DAS shut down shortly after taking office.

Victim representatives at peace talks with the FARC rebels held a press conference in Bogotá Feb. 20 to demand action from the Colombian government over mounting death threats against them. At least 14 of the 60 representatives have received death threats because of their participation—and the son of one representative was killed. Nilson Liz, a regional leader of the National Association of Campesino Land Users (ANUC) from Cauca department, said that following his trip to Cuba for the talks, unknown assailants murdered his son Dayan on Jan. 1. ANUC, which is seeking return of lands stolen by armed groups, has had 90 leaders assassinated since its founding in 1970. (Colombia Reports, Feb. 21; Semana, Feb. 20)
