CAM RANH BAY, Vietnam (AP) — From the flight deck of the USNS Richard E. Byrd, U.S. Defense Secretary Leon E. Panetta could look out across Vietnam's Cam Ranh Bay toward the South China Sea.
A day after laying out details of the Pentagon's new focus on the Asia-Pacific region, Mr. Panetta used a visit to Vietnam to restate the United States' intent to help allies in the region develop and enforce maritime rights in the sea, a waterway largely claimed by China. And he reflected on the significance of the harbor, which represents both a painful past for the American military and a challenging but hopeful future.
"The new defense strategy that we have put in place for the United States represents a number of key elements that will be tested in the Asia-Pacific region," Mr. Panetta told reporters gathered Sunday under a blazing sun on the deck of the cargo vessel. He said the U.S. would "work with our partners like Vietnam to be able to use harbors like this as we move our ships from our ports on the West Coast towards our stations here in the Pacific."
Mr. Panetta never mentioned China as he spoke to crew members on the Byrd and later to reporters. But with the South China Sea as a backdrop, he made it clear that the U.S. will maintain a strong presence in the region and wants to help allies protect themselves and their maritime rights.
His visit here, however, is likely to irritate Chinese leaders, who are unhappy with any U.S. buildup in the region and view it as a possible threat. Mr. Panetta, in remarks Saturday to a defense conference in Singapore, rejected such claims, but U.S. officials are clearly wary of China's increased military buildup and expanding trade relations with other countries in the region.
"Access for United States naval ships into this facility is a key component of this relationship (with Vietnam), and we see a tremendous potential here for the future," Mr. Panetta said.
This is Mr. Panetta's first visit to Vietnam, and his stop at the harbor made him the most senior U.S. official to go to Cam Ranh Bay since the Vietnam War ended.
Right now, U.S. warships do not go into the harbor, but other Navy ships such as the Byrd do. The Byrd is a cargo ship operated by the Navy's Military Sealift Command and it has a largely civilian crew. It is used to move military supplies to U.S. forces around the world. Navy warships go to other Vietnam ports, such as Danang.
While Mr. Panetta suggested the U.S. may want to send more ships to Cam Ranh Bay in the future, he and other defense officials did not detail what requests he may make in meetings with Vietnamese leaders.
During the Vietnam War the strategic deep-water port was used as a base by the U.S. On Sunday, it served more as a symbol of America's growing military relationship with Vietnam, underscoring Washington's desire to build partnerships in the region in part to counter China's escalating dominance.
And for Mr. Panetta, who was in the military during the Vietnam era but did not serve in country, it was an emotional opportunity.
"For me personally this is a very moving moment," he said, noting that on Memorial Day he was at the Vietnam Veterans Memorial in Washington commemorating the 50th anniversary of the war.
"Today I stand on a U.S. ship here in Cam Ranh Bayh Bay to recognize the 17th anniversary of the normalization of relations between the United States and Vietnam," he said.
The relationship between the two nations has come a long way, he said, "We have a complicated relationship, but we're not bound by that history."
The new U.S. strategy for the Asia-Pacific includes a broad plan to help countries learn to better defend themselves, and for that to happen, "it is very important that we be able to protect key maritime rights for all nations in the South China Sea and elsewhere," Mr. Panetta said from the deck of the ship.
China claims almost the entire South China Sea as its own, setting up conflicts with other nations in the region, including Vietnam, Taiwan, Malaysia, Singapore, Brunei and others that also have territorial claims there.
Mr. Panetta flew to Vietnam from a major defense conference in Singapore, where he met with leaders from allies all across the region. There he issued a strong call for Asian nations to set up a code of conduct, including rules governing maritime rights and navigation in the South China Sea, and then develop a forum where disputes can be settled.
At the same time he detailed plans to boost U.S. military presence in the region, including a modest increase in ships and more troops that mainly would rotate in and out. Defense officials said that by 2020 the U.S. Navy would add about eight ships to the Asia-Pacific region and overall would have about 60 percent of the fleet assigned there.
Tensions between the U.S. and China reverberate across the region and often are focused on America's support of the island of Taiwan, which China considers its own.
In addition, more recently the U.S. has been vocal in blaming China for cyberattacks that emanate from the country and steal critical data from U.S. government agencies and private American companies.
