Did China and North Vietnam govt signed in to Geneva Accords 1954 or not ?
They did as a team. The South/US team didn't.
Frankly I don't see any linkage between Geneva Accords 1954 and the territorial disputes at all. Anyway, Let's dissect the information.
The Final Declarations of the Geneva Conference July 21, 1954
4. The Conference takes note of the clauses in the Agreement on the cessation of hostilities in Viet-Nam prohibiting the introduction into Vietnam of
foreign troops and military personnel as well as all kinds of arms and munitions. The Conference also takes note of the declarations made by the Governments of Cambodia and Laos of their resolution not to request foreign aid, whether in war material, in personnel or in instructors except for the purpose of the effective defence of their territory and, in the case of Laos, to the extent defined by the Agreements on the cessation of hostilities in Laos.
- The foreign troops were China for North, US for South/French. China signed the accord because of its assistance to
the North, not because China/North were sorting out territorial dispute friends.
5. The Conference takes note of the clauses in the Agreement on the cessation of hostilities in Viet-nam to the effect that no military base under the control of a foreign State may be established
in the regrouping zones of the two parties, the latter having the obligation to see that the zones allotted to them shall not constitute part of any military alliance and shall not be utilized for
the resumption of hostilities or in the service of an aggressive policy. The Conference also takes note of the declarations of the Governments of Cambodia and Laos to the effect that they will not
join in any agreement with other States if this agreement includes the obligation to participate in a military alliance not in conformity with the principles of the Charter of the United Nations or,
in the case of Laos, with the principles of the Agreement on the cessation of hostilities in Laos or, so long as their security is not threatened, the obligation to establish bases on Cambodian or
Laotian territory for the military forces of foreign powers.
6. The Conference recognizes that the essential purpose of the Agreement
relating to Viet-nam is to settle military questions with a view to ending hostilities and that the military demarcation line
is provisional and
should not in any way be interpreted as constituting a political or territorial boundary. The Conference expresses its conviction that the execution of the provisions set out in the
present Declaration and in the Agreement on the cessation of hostilities creates the necessary basis for the achievement in the near future of a political settlement in Viet-Nam.
- Obviously the demarcation line is solely for the North/South Vietnam forces to comply - sort of no crossing line, and the line did not constitute territorial boundary at all.
