DECISIVE EVIDENCE OF BORDER ENCROACHMENT



 SUMMARY AND CONCLUSIONS





I- My previous work on the border issue (October 2009 - February 2010)



My first purpose was to show that the so-called temporary border post # 185 
made up of six wooden poles which I uprooted on October 25, 2009 in Koh Kban 
Kandal village, in Samraong commune, Chantrea district, Svay Rieng province, 
was located in fact within Cambodia’s territory, at a significant distance from 
the real and legal border between Cambodia and Vietnam, because the poles were 
planted in the middle of a Cambodian farmer’s rice field.



But in the process of doing the limited work as stated above, a team of several 
Cambodian and French experts assisting me has examined the border situation for 
the entire Samraong commune involving four different locations of newly erected 
"border" markers (# 184, 185, 186 and 187). We found that the locations were 
all inside Cambodia. Then we realized that the type of border encroachment we 
discovered in Samraong commune could have as well taken place in other 
communes, other districts and other provinces given the same political and 
administrative context that has prevailed in Cambodia since 1979.   



In January and February this year, we presented evidence of border encroachment 
in two reports available at http://tinyurl.com/yeaoxyf and at 
http://tinyurl.com/ykbq57f.



In the first set of documents, we showed that the newly-planted so-called 
temporary border posts # 184, 185, 186 and 187 in Samraong commune were all 
inside Cambodia whether we based our observations and analyses on the official 
1952 French SGI 1/100,000 map deposited at the UN in 1964, the 1966 US Army 
1/50,000 map or more recent Google Earth satellite imagery. We estimated that 
the four so-called temporary border posts had been wrongfully planted inside 
Cambodia at a distance between 300 meters and 500 meters from the legal 
international border as delineated on both the French map and the US map.   



In the second set of documents, we identified three real and legal border 
points in the vicinity of Samraong commune but in a zone now controlled by 
Vietnam. The geographical coordinates of those border points are specified in 
the 1985 Border Treaty between Cambodia and Vietnam (available at the Council 
of Ministers' website 

http://www.pressocm.gov.kh/border/11.php). As a matter of fact, we could 
confirm that those official border points are effectively located on -- or 
extremely near -- the border line as delineated on existing maps. However, we 
noticed that, on the two recognized maps as well as on satellite imagery, those 
three official border points are located much to the East of the newly-planted 
"temporary border posts" # 184 through 187, meaning that the latter clearly 
encroach on Cambodia’s territory, in stark violation of the 1985 Border Treaty.



Therefore, the so-called temporary border post I pulled out last year (# 185) 
and those nearby (# 184, 186 and 187) were not real border posts: They had been 
illegally planted well inside Cambodian territory, on Khmer farmers’ rice 
fields.



The result of our previous work as described above is now confirmed by the new 
report attached herewith, which is more elaborated, more exhaustive and most 
authoritative.  



II- The new report (March 23, 2010) 



To read the full report please click at http://tinyurl.com/y8s2ntw

  

This 14-page report in French titled "Géoréférencement des Cartes Trang Bang et 
Duc Hue" or Georeferencing of Trang Bang and Duc Hue Maps, was written by Mr 
Régis Caloz, a physicist and map expert specialized in Geographic Information 
System (GIS), who was a professor at the renowned Ecole Polytechnique Fédérale 
de Lausanne, in Switzerland. I was introduced to Mr Caloz by the Geneva-based 
Inter-Parliamentary Union (IPU).



Here are the main points of the report:



1. All the maps and official documents that we have used so far are real, 
genuine and authentic (pages 2 to 4).



2. The analytical methods and tools we used previously were, on the whole, 
accurate. But more sophisticated, more refined and more precise methods and 
tools are used in the new report (pages 4 to 10). 

A theoretical mistake we made previously related to a datum conversion has been 
fixed but with no change whatsoever in the final result (page 10):  “The GPS 
locations under WGS 84, directly converted into UTM 48 without change in the 
ellipsoid and introduced on the (digitalized) Duc Hue map in UTM 48 under 
Everest (India) 60, coincide with the points obtained by following the 
procedure used for the first assumption which logically includes a datum 
conversion.”

["Les points GPS sous WGS 84, convertis directement en UTM 48 sans modification 
de l’ellipsoïde et introduits sur la carte Duc Hue en UTM 48 sous Everest 
(Indes) 60, se superposent aux points obtenus en suivant la procédure de la 
première hypothèse comportant logiquement la conversion de datum."]



3. All the results we found previously are confirmed by the new report, which 
only brings more certainty and more precision to our previous conclusions, in 
particular (pages 10 to 14):



a) The so-called temporary border posts # 184, 185, 186 and 187 are located at 
a distance of respectively 368 m, 319 m, 493 m and 483 m from the real and 
legal border, with a margin of error of plus or minus 100 m. In the worst case, 
those fake and illegal border posts are located at 268 m, 219 m, 393 m and 383 
m from the real and legal border, meaning well inside Cambodia’s territory 
(page 12).



b) Even the controversial 1985 Border Treaty is being violated, with Vietnam 
continuously moving the de facto (imposed) border into Cambodia’s territory. 
The continuous encroachment has followed a two-step process (pages 13 and 14):

- First, the administrative frontier was displaced from the original legal 
border line -- where we can spot the three border points 1985-143, 1985-144 
(very near to Canal 1 on Google satellite imagery, page 14) and 1985-145 -- to 
a more recent canal (Canal 2 on Google satellite imagery) dug in 1979 in 
Cambodia's territory, between 100 m and 300 m to the west of the original legal 
border line. Canal 2 currently represents the de facto border line.

- Second, there is presently an attempt to move again the border line from the 
1979 canal (Canal 2) to the new "temporary border posts" 184, 185, 186 and 187 
planted between 100 m and 300 m further to the West in 2008-2009, infringing on 
rice fields belonging to Cambodian farmers I have been trying to defend.



c) The current government in Phnom Penh has shown its negligence and/or 
incompetence when it comes to dealing with the defense of Cambodia’s 
territorial integrity as enshrined in the 1991 Paris Peace Agreements and in 
the Kingdom’s Constitution.
