Can 23 OCT 1991 Paris Peace Agreements pressure Cambodian Royal Government?

23 OCT 1991 Paris Peace Agreement formally titled Agreements on a Comprehensive Political Settlement of the Cambodia Conflict. ​The agreements were the following conventions and treaties: The Final Act of the Paris Conference on Cambodia Agreement on the Political Settlement of the Cambodia Conflict Agreement Concerning the Sovereignty, Territorial Integrity and Inviolability, Neutrality and National Unity of Cambodia Declaration on the Rehabilitation and Reconstruction of Cambodia ​Can this peace treaty pressure Cambodian Royal Government? 1991 Paris Peace Agreements cannot totally pressure Cambodian Royal Government because of following reasons: 1. The big major parties of the conflict had gone away (Mr. Son Sann, Mr. Son Sen, and Norodom Sihanouk had passed away. Moreover, Mr. Khieu Samphan was given the life sentence). Moreover, the return of Norodom Sihanouk to Cambodia in 1993 and Win-Win Policy (National Reconciliation Policy) from 1996 to 1998 were fully ended civil war, and all parties joined with Mr. Hun Sen. In addition, the creation of Extraordinary Chambers in the Courts of Cambodia (ECCC) was a strategy to destroy Khieu Samphan that was the big major parties in the treaty. 2. The meaning in the treaty have put in the constitute and other domestic laws. This is the reason that Royal Government protect itself efficiently and have enough ability to explain it. 3. The interest of signatories: The countries that don't have benefit from Cambodia, they ignore it. The countries that have  from Cambodia, they protect Cambodia. And the countries that lost their benefits, they bash Cambodia. Most of signatories don't have benefit from Cambodia.  *Note: There are only the big major parties in the agreements or in the conflict that can pressure Cambodian Government to obey the treaty. How can they pressure while we are knowing that they had gone away?
