Sure enough, the spy takes the bait. He reports where the Americans are showing the front line and the HQ Staff figures that their map must be in error and orders the troops to pull back behind the ‘true’ font line.
Obviously Catch 22 was required reading for the PRC Strategic Influence Operations team. According to the Bangkok post of 29 March, the Indonesians are protesting the map that the PRC is using on its passports. (see http://www.bangkokpost.com/breakingnews/342996/indonesia-made-china-passport-complaint which is also the photo source.)
The Chinese are masters of nuance and have been for thousands of years. By printing their perception of borders the Chinese have cleverly managed to tick off one of their Asian neighbors.
Assuming that the move was intentional, this illustrates how the Chinese leadership, department of state and other ministries have all cooperated to influence the outside world at little or no cost. Something that perhaps we could all learn from.
