CARACAS, Venezuela — Peace negotiators for the Colombian government and the country’s largest rebel group said Sunday that they had reached an agreement on a plan to reduce inequality in rural areas.

The deal was announced in Havana, where the two sides have been meeting in an attempt to end the long-running guerrilla war in Colombia. The agreement was seen as an encouraging step, though there are significant obstacles to be cleared before a comprehensive peace accord can be reached.

The agreement announced Sunday calls for the government to distribute land to small farmers and undertake development projects that would improve education and infrastructure, among other measures. It will not take effect until a final peace agreement is reached. The deal took negotiators for the government and the rebels — the Revolutionary Armed Forces of Colombia, or FARC — six months to hammer out; the subject was expected to be one of the less contentious in the talks.

Now the two sides are to turn to thornier issues, including the question of how to clear the way for former guerrillas to participate in politics, how the rebels will be disarmed, and what to do about the drug trafficking that has been a major source of the FARC’s income.
