Secretary of State Rex Tillerson was speaking after a one-day stop in Naypyidaw, as global outrage builds over impunity for a military accused of waging an ethnic cleansing campaign against the Rohingya.
Speaking by his side, Myanmar's de facto civilian leader Aung San Suu Kyi hit back at global criticism that she has been silent over the refugee crisis, saying she has instead focused on speech that avoids inflaming sectarian tensions.
While the army insists it has only targeted Rohingya rebels, refugees massing in grim Bangladeshi camps have described chilling and consistent accounts of widespread murder, rape and arson at the hands of security forces and Buddhist mobs.
Speaking after meetings with the army chief and Suu Kyi, Tillerson said that broad economic sanctions are "not something that I'd think would be advisable at this time".
"We want to see Myanmar succeed," he told reporters. "You can't just impose sanctions and say therefore the crisis is over."
"The scenes of what occurred out there are just horrific," he added.
Both the army and Suu Kyi's administration have dismissed reports of atrocities and refused to grant entry to UN investigators charged with probing allegations of ethnic cleansing.
But Washington has been careful to focus blame on the military rather than Suu Kyi, whose fledgling civilian administration is in a delicate power-sharing arrangement with the army.
Suu Kyi, who rarely holds press conferences, addressed those criticisms on Wednesday.
"I have not been silent... what people mean is what I say is not interesting enough," she told reporters.
"What I say is not meant to be exciting, it's meant to be accurate... not set people against each other."
Suu Kyi's defenders say she must tread lightly to avoid provoking a powerful army that could roll back democratic gains at any time.
Washington rolled back junta-era trade bans and sanctions on military cronies at key points in the transition to encourage progress.
But the Rohingya crisis has pushed US lawmakers to propose a renewal of targeted military sanctions, including import bans on a jade trade run mostly by junta-era cronies.
Tillerson said he would review the bills upon return to Washington.
As anger over the plight of Rohingya mounts abroad, Myanmar's army has dug-in with its denial of abuses -- while also curbing access to the conflict zone.
Rights groups blasted the report as an attempt to "whitewash" atrocities by a military with a long history of abuses, especially against ethnic minorities in border regions.
