[WASHINGTON] President Barack Obama is considering whether to lift the three-decade-old US arms embargo on Vietnam, US officials say, as he weighs calls to forge closer military ties with Hanoi against concerns over its poor human rights record.
The debate within the US administration is coming to a head amid preparations for Mr Obama's trip to Vietnam in the second half of May to bolster ties between Washington and Hanoi, former wartime enemies who are increasingly partners against China's growing territorial assertiveness in the South China Sea.
The full removal of the embargo - something Vietnam has long sought - would sweep away one of the last major vestiges of the Vietnam War era and advance the normalization of relations begun 21 years ago. It would also likely anger Beijing, which condemned Mr Obama's partial lifting of the arms ban in 2014 as an interference in the region's balance of power.
On one side of the internal debate, some White House and State Department aides say it would be premature to completely end restrictions on lethal military assistance before Vietnam's communist government has made more progress on human rights.
They are at odds with other officials, including many at the Pentagon, who argue that bolstering Vietnam's ability to counter a rising China should take priority, according to people with knowledge of the discussions.
Boosting the security of allies and partners has been a major thrust of Mr Obama's strategic "pivot" toward the Asia-Pacific region, a centrepiece of his foreign policy.
Even as Vietnam seeks warmer relations with the United States, though, US officials are mindful that suspicions linger among Communist Party conservatives that Washington wants to undermine their country's one-party system.
One major factor in Mr Obama's decision will be whether Vietnam will move forward on major US defense deals, a potential boon for American jobs that could soften congressional opposition to lifting the weapons ban, according to one source close to White House policymaking.
There have been questions about whether Vietnam, which has relied mostly on Russian weapons suppliers since the Cold War, is ready to start buying US-made systems. Diplomats have seen increasing signs that Hanoi is seeking ties with US defense contractors but Washington wants tangible commitments, according to the source.
Vietnam is big buyer of weapons from Russia, its Cold War-era patron, including Kilo-class submarines and corvettes. It could look to the United States for items such as P-3 surveillance planes and missiles to beef up its naval forces and coastal defenses.
At the Pentagon, the prevailing view appears to be more in line with Defense Secretary Ash Carter's congressional testimony late last month that he would support lifting restrictions on the sale of US weapons to Vietnam.
That comment raised eyebrows at the White House, where officials said Mr Obama had yet to rule on the issue.
Mr Obama's final decision could hinge on whatever recommendations come from a visit to Vietnam early this week by Daniel Russel, the assistant secretary of state for East Asia and the Pacific, and Tom Malinowski, the administration's top human rights envoy.
It was not clear whether Mr Obama was leaning for or against ending the embargo ahead of his trip, which will make him the third consecutive US president to visit Vietnam.
Mr Obama eased the ban on lethal arms sales to Vietnam in October 2014, allowing shipments of defensive maritime equipment to help Hanoi build up its deterrent to China's pursuit of its claims in the South China Sea, which conflict with those of its neighbors such as Vietnam and US ally the Philippines.
John Sifton, Asia advocacy director for Human Rights Watch, said lifting the arms ban would be "undeserved at this time".
The group, in an April 27 letter sent to Mr Obama, described the Vietnamese government as "among the most repressive in the world." While a number of US lawmakers favor closer military ties with Vietnam because of shared concerns about China, others have deep misgivings.
Democratic US Representative Loretta Sanchez, a member of the Congressional Caucus on Vietnam who also has a large Vietnamese-American voting bloc in her California district, said lifting the embargo would be "giving a free pass to a government that continually harasses, detains and imprisons its citizens."
Mr Obama has the power to bypass Congress to lift the embargo. But his administration would hope for support from Republican US senator John McCain, a decorated former prisoner of war in North Vietnam who backed the 2014 partial lifting.
Some US officials see signs that Vietnam is starting to pay attention to human rights criticism. But concerns remain over the government's heavy-handedness toward political opponents and treatment of workers and there is worry that Washington will lose some leverage if it gives up the arms embargo without securing concessions for reforms.
One senior US official suggested that it might be best for now to "set the issue of the lethal weapons ban aside." "These things do take time," the official said. But others said the door should remain open to lifting the embargo as preparations proceed for Mr Obama's visit.
If Mr Obama opts against removing the ban for now, another option that might mollify the Vietnamese would be creating a "working group" to map out the path toward doing so, one US official said.
