Deputy National Security Adviser Ben Rhodes told reporters he will meet with Shui Meng Ng on Thursday while Obama is visiting Laos. The president arrived yesterday to attend a regional summit.
Human rights activists were hoping that Obama would speak about Ng's husband, Sombath Somphone, who was picked up apparently by security forces on December 15, 2012.
He has not been seen since.
He said he also met Ng during a recent visit to Laos, and planned to stay in "regular contact" with her. Rhodes said the Laotian government has told the US the same thing it tells Sombath's wife - that it's looking into his disappearance.

"Oftentimes, they indicate that they do not know, and that there's an ongoing investigation," Rhodes said.
He said that typically, Obama addresses human rights issues with foreign leaders more broadly, and lets his staff raise specific cases with their counterparts.
Within a few minutes a man on a motorcycle arrives, drives away Sombath's vehicle, and a pickup truck takes Sombath away with armed people on a motorcycle leading the way. The passenger on the motorcycle fires a gunshot into the air, Amnesty International said.
The human rights group said it believes the authorities are either directly responsible for his disappearance, or have simply failed to take steps to find out what happened to him.
The message has to be clear that the cover up has to end, Sombath needs to be found, and that no other outcome is acceptable," Phil Robertson, deputy director for Asia at Human Rights Watch, said today.
