MEXICO CITY — Secretary of State Hillary Clinton ended a five-day tour of Latin America Friday with a lightning trip to Guatemala, where she promised Central American presidents more help to fight drug trafficking and repeated her call for more countries to recognize the new government of Honduras.

The new Honduran president, Porfirio Lobo, attended the meeting in Guatemala City, an appearance that signaled a step toward normalizing relations with neighbors El Salvador and Guatemala.

Many countries in the hemisphere have refrained from recognizing Mr. Lobo’s government because it came to power with an election held under a government installed by a coup last June. Washington has argued that Mr. Lobo was chosen in fair elections that had been scheduled before the coup.

On Thursday in San Jose, Costa Rica, Ms. Clinton announced that the United States was restoring more than $30 million in aid to Honduras it had suspended after the coup.
