This is just another ridiculous act on the part of Chinese government not to stamp the Indian passport of Indian citizens living in Arunachal Pradesh who are going to visit China, and rather the Chinese government issues a separate paper with the Chinese visa.  They had done the same thing for the Indian citizens living in Srinagar area.  Chinese action leads one to believe that the Chinese Government does not consider Arunachal Pradesh and Srinagar as part of India - these are disputed territories in the eyes of China.  Basically, this shows China's insatiable territorial ambition.  They are encroaching in Bhutan, have forcefully occupied Tibet since 1959, have been occupying thousand and thousand square miles of Indian territory in Ladakh/Leh  area since 1962.  They just walk into another countries' territories freely.  It appears that their increasing economic and military power have put a blinder in front of their eyes and they do not see and care of anything except to fulfill their desire to expand their empire.  I think it is about time that India takes up this issue at all international forums and reverse Chinese attitude so that Chinese can respect and honor the integrity and sovereignty of other countries.  When Sadam Hussain invaded Kuwait, the whole civilized world woke up and stood against Sadam Hussain.  Rest is history.  Now China is slowly and slowly pilfering the territories of other countries, one wonders why the civilized world is not paying any attention to Chinese activities and condemn them.  It sounds like a dual policy.  May be in case of Kuwait, western nations' economic interest  (OIL) was involved and in case of India and other small countries neighboring China, there is no economic interest involved.  Anyhow, whatever the reason may be, it is about time that the western nations take note of what China is doing to establish its own hegemony in Asia, if not worldwide, before it is too late.
