BANGKOK -- On her second trip to Asia as U.S. secretary of state, Hillary Rodham Clinton is carrying a no-nonsense message about American intentions.
"The United States is back," she declared upon arrival in the Thai capital.
And in an appearance Wednesday morning on a Thai TV talk show she said, "President Obama and I are giving great importance to this region," suggesting that the administration of former President George W. Bush neglected U.S. interests in Asia.
Evidence of the new U.S. approach, she said, is the fact that her first overseas trip, in February, was to Asia.
"I believe strongly the United States has to be involved in this region," she added. Her main aim in visiting Southeast Asia this time, she said, is to "work hard to try to bring a sense of future possibilities" for partnerships to ensure peace and prosperity.
Asked whether the Bush administration made a mistake by not putting more diplomatic effort into U.S. relationships in Asia, Clinton replied by saying that in last November's election, "the American people made a very definite decision."
The administration of President Barack Obama thinks it's time to show Asian nations that the United States is not distracted by its wars in Iraq and Afghanistan and intends to broaden and deepen its partnerships in this region.
Clinton says that in Phuket she will sign ASEAN's seminal Treaty of Amity and Cooperation, a commitment to peacefully resolve regional disputes that already has been signed by more than a dozen countries outside the 10-nation bloc.
The U.S. signing will be by the executive authority of Obama and does not require congressional ratification, said a senior administration official who spoke on condition of anonymity because he was not authorized to discuss the move publicly.
The Bush administration had declined to sign the document, whereas Obama sees it as a symbolic underscoring of the U.S. commitment to Asia.
On her arrival here Tuesday, Clinton reiterated Obama administration concerns that North Korea, already a threat to the U.S. and its neighbors with its history of illicit sales of missiles and nuclear technology, is now developing ties to Myanmar's military dictatorship.
Clinton held out the possibility of offering North Korea a new set of incentives to return to negotiating a dismantling of its nuclear program if it shows a "willingness to take a different path." But she admitted there is little immediate chance of that.
A Clinton aide said the United States and its allies are looking for a commitment by North Korea that would irreversibly end its nuclear weapons program. The aide, who spoke on condition of anonymity to discuss internal U.S. government deliberations, said there is no sign that North Korea intends to make such a move, keeping the U.S. focus on enforcing expanded U.N. sanctions.
In her remarks about a possible Myanmar-North Korea connection, Clinton did not refer explicitly to a nuclear link but made clear that the ties are disconcerting.
"We know there are also growing concerns about military cooperation between North Korea and Burma which we take very seriously," she said at a news conference in the Thai capital.
"It would be destabilizing for the region, it would pose a direct threat to Burma's neighbors," she said, adding that as a treaty ally of Thailand, the United States takes the matter seriously.
Later, a senior administration official said that Washington is concerned about the possibility that North Korea could be cooperating with Myanmar on a nuclear weapons program, but he added that U.S. intelligence information on this is incomplete. The official spoke on condition of anonymity because of the sensitive nature of the matter.
The United States, in a joint effort with South Korea, Japan, China and Russia, is attempting to use U.N. sanctions as leverage to compel North Korea to return to the negotiating table over its nuclear program. A major element of the international concern about North Korea is the prospect of nuclear proliferation, which could lead to a nuclear arms race in Asia and beyond.
Clinton spoke to reporters after meeting with Thai Prime Minister Abhisit Vejjajiva at the outset of a three-day visit to Thailand.
Clinton sharply criticized the military rulers of Myanmar for human rights abuses, "particularly violent actions that are attributed to the Burmese military concerning the mistreatment and abuse of young girls."
She said an Obama administration policy review on Myanmar is on hold pending the outcome of the trial of democracy leader Aung San Suu Kyi, who is accused of violating the terms of her house arrest. The Noble Peace Prize laureate faces up to five years in prison if convicted, as expected.
In Washington, the U.S. House of Representatives voted to renew sanctions aimed at penalizing the country's ruling junta. The resolution approving the reauthorization of the sanctions now goes to the Senate for consideration.
The resolution renews sanctions targeting imports from Myanmar and also maintains a ban on importing jade and other gems from Myanmar. The legislation was first enacted in 2003.
