This weekend's arrival of a U.S. aircraft carrier in the 
Yellow Sea  poses a dilemma for 
Beijing: Should it protest angrily and aggravate  ties with 
Washington, or quietly accept the presence of a key symbol of  
American military pre-eminence off 
Chinese shores?
The 
USS George Washington,  accompanied by escort ships, is to take part in military drills with  
South Korea following
 North Korea's shelling of a 
South Korean island  Tuesday that was one of the most serious confrontations since the 
Korean  War a half-century ago.
It's a scenario 
China has sought to prevent. Only  four months ago, 
Chinese officials and military officers shrilly warned  
Washington against sending a carrier into the Yellow Sea for an earlier  set of exercises. Some said it would escalate tensions after the sinking  of a 
South Korean navy ship blamed on 
North Korea. Others went further, calling the carrier deployment a threat to 
Chinese security.
Beijing believes its objections worked. Although 
Washington never said why, no 
aircraft carrier sailed into the strategic Yellow Sea, which laps at several 
Chinese provinces and the 
Korean peninsula.
This time around, with outrage high over the  shelling, the 
U.S. raising pressure on 
China to rein in wayward ally  
North Korea, and a 
Chinese-American summit in the works, the warship is  coming, and Beijing is muffling any criticisms.
"One of the results of 
North Korea's most recent  belligerence has been to make it more difficult for 
China to condemn 
 U.S. naval deployments in the East 
China Sea,"  said Michael Richardson, a visiting research fellow at Singapore's  Institute of Southeast Asian Studies. "I think 
China must be quietly  cursing 
North Korea under their breath."
China's response has so far been limited to  expressing mild concern over the exercises. A Foreign Ministry spokesman  on Friday reiterated 
Beijing's long-standing insistence that foreign  navies obtain its permission before undertaking military operations  inside 
China's exclusive economic zone, which extends 230 miles (370  kilometers) from its coast.
It wasn't clear where the drills were being held or if they would cross into the 
Chinese zone.
The statement also reiterated calls for calm and restraint but did not directly mention the Yellow Sea or the planned exercises.
State media have been virtually silent. An editorial  in the nationalistic tabloid Global Times worried that a 
U.S. carrier  would upset the delicate balance in the Yellow Sea, ignoring the fact  that the 
George Washington has taken part in drills in those waters  numerous times before.
North Korea, by contrast, warned Friday that the  
U.S.-South Korean military drills were pushing the peninsula to the  "brink of war."
A more passive approach this time helps Beijing raise  its credibility with Washington and trading partner 
South Korea, and  puts 
North Korea on notice that its actions are wearing 
China's patience  thin.
"The 
Chinese government is trying to send 
Pyongyang a  signal that if they continue to be so provocative, 
China will just  leave the 
North Koreans to themselves," said Zhu Feng, director of  Peking University's Center for International and Strategic Studies.
Sending signals is likely to be as far as 
Beijing  goes, however. 
China fears that tougher action — say cutting the food  and fuel assistance Beijing supplies — would destabilize the isolated 
 North Korean dictatorship, possibly leading to its collapse. That could  send floods of refugees into northeastern 
China and result in a pro-
U.S.  government taking over in the North.
"What 
China should do is make the 
North Koreans feel that they have got to stop messing around," Zhu said.
China may also be mindful of its relations with key  trading partner 
Seoul, strained by 
Beijing's reluctance to condemn  Pyongyang over the March ship sinking. Raising a clamor over upcoming  drills in the wake of a national tragedy would only further alienate  
South Korea.
Beijing's mild tone also shows its reluctance to  spoil the atmosphere ahead of renewed exchanges with 
Washington.  President Hu Jintao is scheduled to make a state visit to 
Washington in  January hosted by President 
Barack Obama — replete with a state dinner  and other formal trappings that President 
George W. Bush never gave the 
 Chinese leader.
Before that Gen. Ma Xiaotian, one of the commanders  who objected to the 
George Washington's deployment earlier this year, is  due in 
Washington for defense consultations. Those talks are another  step in restoring tattered defense ties, a key goal of the 
Obama  administration. 
Chinese fixations about aircraft carriers verge on the visceral. 
U.S.  carriers often figure in 
Chinese media as a symbol of the American  government's ability to project power around the world. The 
Chinese navy  is building a carrier, and keeping 
U.S. ones out of 
China's waters is  seen as rightful deference to its growing power. 
The 
U.S. is worried about a key principle: the 
U.S. Navy's right to operate in international waters. 
While 
China doesn't claim sovereignty over the entire Yellow Sea, it has  become assertive about its maritime territorial claims and sensitive to  
U.S. Navy operations in surrounding waters. In the 
South China Sea, which 
China claims in its entirety, 
China has seized foreign fishing boats and harassed 
U.S. Navy surveillance ships. 
In light of such trends, 
China's protests of the September drills  virtually compelled the 
U.S. Navy to send the 
George Washington this  time, said Alan Romberg of the Stimson Center think tank in 
Washington,  who met with 
Chinese military commanders in the summer. 
"The People's Liberation Army thinks it achieved an initial victory in  keeping the 
U.S. from deploying the George Washington in that first  exercise. That guarantees that the George Washington will go there at  some point, probably sooner rather than later," Romberg said in an  interview in September. 
Even if 
China's reticence holds this time, 
Beijing is not likely to cede  the 
U.S. Navy carte blanche to range throughout the Yellow Sea. 
Foreign Ministry spokesman Hong Lei has stated that 
China's stance on  
U.S. naval action in the Yellow Sea remains unchanged. The politically  influential and increasingly vocal military is also likely to keep the  pressure on the leadership to take a firm stand. 
Any affront to 
Beijing's authority or intrusion into 
Chinese territorial  waters would inflame the 
Chinese public and require a government  response, said Fang Xiuyu, an analyst on 
Korean issues at Fudan  University's Institute of International Studies in 
Shanghai. 
"We hope that the 
U.S. can exert restraint and not cross that line," Fang said.
