The stamps were jointly designed by China Post and Pakistan Post, and feature the sister-ports of Gwadar in Pakistan’s Balochistan Province and Zhuhai in China’s Guangdong Province. Sister-city relations between Gwadar and Zhuhai were established in 2015, during the visit of Chinese President Xi Jinping to Pakistan. Speaking at the occasion, the Ambassador noted that the stamps were an invaluable chronicle of the seven splendid decades of the Pakistan-China All-Weather Strategic Cooperative Partnership, and signify our unique and ironclad friendship. The choice of Gwadar and Zhuhai reflected the steadily expanding friendship and cooperation between the governments and peoples of Pakistan and China along the road to shared prosperity through the China-Pakistan Economic Corridor, a flagship of the Belt and Road Initiative (BRI). The ceremony was also attended by social-sector organizations, media, and stamp collectors, who participated in a lucky draw to receive stamps signed by the Ambassador.
