On November 23, 2013, China's Ministry of National Defense spokesman
announced that a new air defense intercept zone (ADIZ) will be
established by the government to include the Diaoyu, or Senkaku Islands.
Sovereignty over these islands is disputed by Japan, China, and Taiwan.
The new ADIZ also included a submerged rock that falls inside
overlapping Exclusive Economic Zones (EEZ) claimed by China, Japan, and
South Korea. Pundits and policy analysts quickly engaged in a broad
debate about whether China's expanded ADIZ is designed to create tension
in Asia, or is part of a broader plan to impose a new definition of
China's territorial space in the Asia-Pacific region. Meanwhile, to deal
with cyber penetrations attributed to the Chinese People's Liberation
Army (PLA), the U.S. Departments of Justice, Homeland Security, and
State are devising new means to protect intellectual property and
secrets from the PLA's computer network operations.
