BEIJING, June 15  -- Foreign Ministry spokesperson Lu Kang said Wednesday that Chinese frontier guards carried out routine patrols on the China-controlled side of border with India.

Indian media quoted Indian defense and intelligence officials as saying that about 250 Chinese soldiers made "incursion" in the so-called "Arunachal Pradesh" region.

In response to a question in this regard at a regular press briefing, Lu also noted that the boundary between China and India has not been demarcated.
