The removal of the seal of the Office of the President from the face of the stamps was done to give space for a much bigger image since the size of the definitive stamps are smaller. The printing of the 68M was to augment the dwindling supply of P5.00 denomination in post offices nationwide.

The Philippines and the People's Republic of China signed on 09 June 1975 the Joint Communique establishing diplomatic relations between them. Since then, relations between the two countries have evolved into one of the most important bilateral ties the Philippines has forged. The past twenty-five years bear witness to the increasing vibrancy of these relations.

Throughout the twenty-five years, the Philippines and China have exchanged high-level visits such as the State Visits to China of Philippine Presidents Ferdinand E. Marcos, Corazon C. Aquino, Fidel V. Ramos and Joseph Ejercito Estrada. Similarly, Chinese President Jiang Zemin, Premiers Zhao Ziyang, Li Peng, and Zhu Rongji visited the Philippines. These exchanges illustrate the significant strides already taken in the relationship between the two countries, a relationship firmly guided by the principles of mutual respect for sovereignty, territorial integrity, non-aggression, non-interference in each other's internal affairs, and equality.
