Japanese naval and air force commanders suspended trips to South Korea which had been scheduled to start on Monday as part of a military exchange program, the South's defense ministry said.

At the opening ceremony, President of the Korea-Vietnam Friendship Association (KOVIFA) Choi Young-joo emphasized that the RoK and Vietnam share many historical and cultural similarities and have made joint efforts to develop prosperous nations and happy people in a peaceful, friendly and cooperative environment.

Kazuo Korenaga, executive director of the Japan-Korea Economic Association in Tokyo, a group that seeks to promote business and cultural exchange between the two countries, said that, “Politics should be politics, the economy should be the economy. Economic sectors, including the treatment of South Korean stars in the Korean boom, should not be influenced by this issue.”

The spat between Japan and South Korea over two islets, known as Dokdo in Korean, Takeshima in Japanese, and Liancourt Rocks in some international registers, has been propelled into global headlines by an unusual convergence of events.

The "Korean Wave," known as "hallyu," began when the MBC TV soap opera "What is Love?" became a sensation in China after being first broadcast on the state-run CCTV channel in 1996. The Chinese audience response to "Daejanggeum (Jewel in the Palace)," a Korean costume drama starring Lee Young-ae and shown in the country in 2005, was also explosive.

As the United States embarks on a strategic “rebalance” toward Asia, Washington and its allies in the region must do a better job making the case for policies that require broad public support. This is especially true in fiscally constrained times, when the threat of sequestration may require the United States to rely more heavily on its friends and allies in the region.

South Korea's president on Friday made a surprise, election-year visit to islets also claimed by Japan, which quickly reasserted its sovereignty there, recalled its ambassador from Seoul and warned that the trip would worsen the countries' strained relations. President Lee Myung-bak's trip to the tiny, rocky outcroppings between the countries was the first by a South Korean president, officials in his office said.

She said that rumors in South Korea that the U.S. was exporting cows infected with mad cow disease spread through SNS, fueling anti-U.S. sentiment and nation-wide protests, and hindering free trade negotiations between the two countries. Esser said in such cases, however, the majority of the online community tends to shout down the extremists, working as a “self-correcting mechanism.”
