Panetta met with Chinese leader-in-waiting Xi today, who just days ago reappeared after a puzzling two-week absence. Panetta told the press his “impression was that he was very healthy and very engaged." He also ate lunch with and spoke to cadets at the Armored Forces Engineering Academy where he reassured them about America's plans to put a second radar system in Japan. "Our rebalance to the Asia-Pacific region is not an attempt to contain China," he said. "It is an attempt to engage China and expand its role in the Pacific. It is about creating a new model in the relationship of two Pacific powers."
Panetta is on the second stop of a three nation tour to Japan, China and New Zealand.

The announcement came as U.S. Defense Secretary Leon Panetta and Vietnam Defense Minister Phung Quang Thanh exchanged long-held artifacts collected during the war -- including letters written by a U.S. soldier who was killed that had been kept and used as propaganda, and a small maroon diary belonging to a Vietnamese soldier. A U.S. service member took the journal back to the U.S. Full story.

U.S. Secretary of Defense Leon Panetta and Libyan Prime Minister Abd al-Rheem Al-Keeb greet one another during their joint news conference in Tripoli, Libya, Saturday, Dec., 17.
TRIPOLI - U.S. Defense Secretary Leon Panetta arrived in Tripoli Saturday, taking advantage of the ouster of Moammar Gadhafi in an eight-month civil war to become the first Pentagon chief to set foot on Libyan soil.
But Panetta has indicated that the U.S. will give more time to gain control of the militias that overthrew Gadhafi before determining how to help the fledgling government.
"The last thing you want to do is to try to impose something on a country that has just gone through what the Libyans have gone through," said Panetta on Friday before landing in Tripoli.
"They've earned the right to try to determine their future. They've earned the right to try to work their way through the issues that they're going to have to confront," he said.

Travels with Leon Panetta
It's been a busy week for the Secretary of Defense. Three days ago he was in Djibouti, in the Horn of Africa. He then moved on to Kabul where he presented Purple Hearts to members of the armed forces, and yesterday he took part in the ceremony in Baghdad marking the end of the U.S. military's mission in Iraq. Today he is in the Turkish capital, and he is also due to visit Libya on what The Associated Press described as his "holiday tour".

As US shifts military focus, Sec. Leon Panetta visits troops in Djibouti
NBC News, msnbc.com staff and news services report:
As the U.S. winds down operations in Iraq and begins its methodical withdrawal from Afghanistan, the U.S. military has increasingly focused on Africa — particularly the north, where insurgents have found sanctuary.
The military base in the tiny port nation of Djibouti is the launchpad for U.S. drones used for intelligence, surveillance and, at times, strikes against insurgents in terror hotspots. The more than 3,000 U.S. service members assigned represent all U.S. military services, including 500 members of the National Guard, NBC News reported.

Defense Secretary Leon Panetta and Chairman of the Joint Chiefs of Staff Adm. Michael Mullen testify before the Senate Armed Services Committee, Thursday, Sept. 22, in Washington, D.C. Panetta and Mullen testified before the committee on U.S. strategy in Afghanistan and Iraq.
AP reports that Defense Secretary Leon Panetta and Chairman of the Joint Chiefs of Staff Adm. Michael Mullen accused Pakistan of "exporting violence" to Afghanistan, putting in jeopardy the delicate U.S.-Pakistani partnership against terrorism and possibly a successful outcome to the war in Afghanistan. The two were testifying at a Senate Armed Services Committee hearing on U.S. strategy in Afghanistan and Iraq.
Maybe Mullen was feeling like he could be a little more honest since he's retiring next week. Or it could be the start of the administration taking a more critical approach to an ally.

Update: The New York Times reports that Panetta and Mullen also said that the Pakistani spy agency, the I.S.I., had a direct role supporting the militants in the attack on the U.S. Embassy in Kabul last week. Full story.
