South China's Jiangxi Province and its sister-province, Bohol Province of the Philippines, unveiled a first-edition commemorative stamp cover on October 12, 2010 in Lushan Mountain of Jiangxi Province.
As part of the Sino-Philippines Stamp Exhibition, it was designed to celebrate the 35th anniversary of Sino-Philippines diplomatic relations and the twinning relations between Jiangxi Province and Bohol Province of the Philippines.
As a project between the sister-provinces, the envelope was considered a historic first in Chinese philatelic history. It featured Jiangxi's Lushan Mountain and the white crane, and Bohol's Chocolate Hills and a big-eyed monkey. It also had commemorative stamps and postmarks on it. A total of 2,000 copies were produced. These were issued in line with China's diplomatic commemorative envelopes, which were a historic first in the world's philatelic history.
Fu Kecheng, chairperson of the Jiangxi Provincial Committee of the Chinese People's Political Consultative Conference (CPPCC), and Edgar M. Chatto, governor of Bohol Province, exchanged presents at the unveiling ceremony.
Ms. Maria Teresa T. Almojuela, Minister and Consul General of the Embassy of the Republic of the Philippines, donated books to pupils at the Lushan No. 1 Primary School in Jiujiang City of Jiangxi Province.
Jiangxi and Bohol became sister provinces on May 8, 2006. In October the same year, Lushan Mountain and Chocolate Hills became sister mountains.
After the ceremony, the participants viewed the Sino-Philippines Stamp Exhibition, which displayed 30 albums of stamps and 480 stamp mounting papers from Bohol Province, the China Post Stamps Museum, the Philatelic Association of the Ministry of Foreign Affairs, and the Jiangxi Provincial Philatelic Association.
