              B-29 (1). PROTOCOL OF AMENDMENT TO THE                          
          INTER-AMERICAN TREATY OF RECIPROCAL ASSISTANCE                      
                                                                              
                                                                              
1.    Bolivia:                                                                
                                                                              
      (Declaration made at the time of signature)                             
                                                                              
      Bolivia signs this Protocol of Amendment to the Inter-                  
American Treaty of Reciprocal Assistance without reservation in the           
conviction that this Protocol updates and improves the stipulations           
of the original instrument in the light of the changed                        
circumstances.                                                                
                                                                              
2.    El Salvador:                                                            
                                                                              
      (Declaration and reservation made at the time of signature)             
                                                                              
      The Delegation of El Salvador states its firm conviction that           
no provision of this Protocol impairs the principle of hemispheric            
solidarity in the face of aggression, whatever its origin may be.             
Without prejudice to any other reservations the Government of the             
Republic may make in due course, it signs this Protocol with the              
reservation that its articles contain no commitment by the Parties            
to use compulsory methods or procedures for the settlement of                 
disputes, which El Salvador cannot accept.                                    
                                                                              
3.    United States:                                                          
                                                                              
      (Reservation made at the time of signature)                             
                                                                              
      The United States, in signing this Protocol of Amendment to             
the Inter-American Treaty of Reciprocal Assistance, accepts no                
obligation or commitment to negotiate, sign or ratify a treaty or             
convention on the subject of collective economic security.                    
                                                                              
                                                                              
4.    Guatemala:                                                              
                                                                              
      (Reservation made at the time of signature)                             
                                                                              
      On signing this Protocol, Guatemala reiterates the reservation          
it made on ratifying the Inter-American Treaty of Reciprocal                  
Assistance, which reads:  "The present Treaty poses no impediment             
whatever to Guatemala's assertion of its rights over the Guatemalan           
Territory of Belize by whatever means it                                      
considers most appropriate; a Treaty that may at any time be invoked          
by the Republic with respect to the aforesaid territory."                     
                                                                              
5.    Mexico:                                                                 
                                                                              
      (Declarations made at the time of signature)                            
                                                                              
      1.    The Delegation of Mexico reiterates its conviction                
that, in establishing the boundaries of the security zone as                  
indicated in Article 4, regions protected by other international              
instruments that have been expressly or tacitly approved by the               
United Nations should, as far as possible, not have been included.            
                                                                              
      2.    The Delegation of Mexico continues to consider that,              
except in case of self-defense, the collective measures to which              
Article 8 refers cannot be applied in mandatory form, given their             
coercive nature, without authorization by the Security Council of             
the United Nations.                                                           
                                                                              
6.    Panama:                                                                 
                                                                              
      (Declaration made at the time of signature)                             
                                                                              
      Panama signs this Protocol of Amedment to Inter-American                
Treaty of Reciprocal Assistance with the reservation that the new             
text can only be accepted with the provisions of the Constitution of          
Panama with respect to the ratification of treaties; in the                   
meantime, Panama will not accept any new clause that might be in              
contravention of the mandates of the Political Constitution of the            
Republic of Panama or the national interest.                                  
                                                                              
7.    Paraguay:                                                               
                                                                              
      (Reservation made at the time of signature)                             
                                                                              
      In signing the Protocol of Amendment ad referendum, the                 
Delegation of Paraguay makes an express reservation concerning                
Article 20, on the grounds that it is inappropriate to use different          
criteria for applying measures and for removing them; this is                 
tantamount to requiring different majorities for the two cases.  The          
Delegation of Paraguay therefore considers that since the decisions           
or recommendations of the Organ of Consultation must be adopted by            
a two-thirds vote of the States Parties, a two-thirds vote of those           
States must also be required to rescind them.                                 
                                                                              
                                                                              
8.    Peru:                                                                   
                                                                              
      (Reservation made at the time of signature)                             
                                                                              
In signing the Protocol of Amendment to the Inter-American Treaty of          
Reciprocal Assistance, Peru makes an express reservation with regard to       
Article 3, paragraph 3.                                                       
                                                                              
a.    United States:                                                          
                                                                              
      (Reservation made at the time of ratification)                          
                                                                              
With the reservation made at the time of signature.                           
                                                                              
b.    Guatemala:                                                              
                                                                              
      (Reservation made at the time of ratification)                          
                                                                              
The present Treaty poses no impediment whatever to Guatemala's                
assertion of its rights over the Guatemalan territory of Belize by            
whatever means it considers most appropriate; a Treaty that may at            
any time be invoked by the Republic with respect to the aforesaid             
territory.                                                                    
                                                                              
      The Government of Guatemala declares formally that this                 
reservation does not imply any alteration in the Inter-American               
Treaty of Reciprocal Assistance, and that Guatemala is ready to act           
at all times within the bounds of international agreements to which           
it is a party.                                                                
                                                                              
c.    Mexico:                                                                 
                                                                              
      (Declaration made at the time of ratification)                          
                                                                              
The Government of Mexico continues to consider that, except in case           
of self-defense, the collective measures to which Article 8 refers            
cannot be applied in mandatory form, given their coercive nature,             
without authorization by the Security Council of the United Nations.          
                                                                              
d.    Peru:                                                                   
                                                                              
      (Declaration and reservation made at the time of                        
      ratification)                                                           
                                                                              
      The Government of Peru upon ratifying the present Protocol              
raiterated and maintained an express reservation to number 3 of               
article 3 of the referred Protocol. The expressed reservation  had            
already been formulated by the Government of Peru in the signatory            
act.                                                                          
                                                                              
      The Goverment of Peru formally declared that it reaffirms its           
complete compliance with the principles which the Interamerican               
System upholds, in particular those of nonintervention with respect           
to treaties and regional                                                      
solidarity.
