According to a Pentagan study, released Wednesday, China is seeking technology and weapons to disrupt the traditional advantages of American forces.

The annual report from the Defense Department to Congress, “Military Power of the People’s Republic of China 2009,” catalogs the efforts by China to supply its armed forces with weapons. These weapons can be used to intimidate and attack Taiwan and blunt the superiority of American naval and air power.

“We have advocated time and again for more dialogue and transparency in our dealings with the Chinese government and military, all in an effort to reduce suspicions on both sides,” said Geoff Morrell, the Pentagon press secretary.

He said the report should be read as calling “for deeper, broader, more high-level contacts with the Chinese.”
