U.S. President Barack Obama's first big speech on Asia, delivered Saturday morning in Tokyo, had a little something for just about everyone. He was tough on North Korea and Myanmar, but offered a way back to the fold.

He was big on Japan and on China, whose rise, he said, should be welcomed, not feared.

India, however, got skipped over. And Taiwan was off his radar.

Interrupted several times by applause and met at the end by a standing ovation, the speech was intended to underscore Obama's desire to engage with the world's most populous region. He concluded by calling himself "America's first Pacific president."

China welcomed Obama's comments that growing economic success there can benefit all.

"We welcome America displaying a constructive approach to the peace, stability and prosperity of the Asia-Pacific region," Chinese Ministry of Foreign Affairs spokesman Qin Gang said in a statement.

"A good China-U.S. relationship is not only beneficial to both countries and to the people of both countries, but it also benefits the peace and development of the Asia-Pacific region and the world."

Still, others thought Obama went too easy on Beijing.

"The United States has high expectations for closer ties with China, as part of a trilateral partnership of the world's top three economies," Takehiko Yamamoto, an international relations professor at Tokyo's Waseda University, said. "But when it comes to national security, China is a major concern and a destabilizing factor for the Japan-U.S. alliance."

Some observers in Taiwan shared that view.

Lo Chih-cheng, a political science professor at Taipei's Soochow University, said Obama's engagement policy may send a signal to the region that China is no longer a security threat, although it is improving its military and expanding the Chinese fleet.

"Obama must not simply say 'yes' to China, but rather say 'no' when he needs to," Lo said. "His stressing engagement with China will raise the question of what priority the U.S. gives to its security treaty with Japan."

North Korea was the target of Obama's most pointed remarks — but he added to that a tone of conciliation, a possible future of economic opportunity and greater global security and respect.

A senior South Korean official said that message shows Obama and South Korean President Lee Myung Bak agree on the need to draw Pyongyang back into the international fold without confrontation, and to convince the regime of the benefits of engagement.

"President Obama reaffirmed the message that the United States has consistently been sending, which is that there's a chance for North Korea to improve the lives of its people if it chooses another path," the presidential official said, asking not to be named because of diplomatic protocol.

"This is the same line as what our president has been saying," he said in Singapore, where Lee is attending a summit of Asia-Pacific leaders.

Obama did not touch on India, which raised some eyebrows.

Ramon Navaratnam, chairman of independent Center for Public Policy Studies, a think tank in Kuala Lumpur, said that was an oversight.

"He may be making a mistake if he overconcentrates on one big giant, China, at the expense of the other big giant, India," he said.

But he added by giving the speech Obama is showing he is changing direction from the previous U.S. leadership to be more engaged with Asia. Navaratnam said previous presidents "sounded condescending and somewhat aloof."

"He's realistic in recognizing the rising power, not only of China, but also the whole of Asia," he said.
