A book stating the undisputable case for Vietnam’s sovereignty over Hoang Sa (Paracel) and Truong Sa (Spratly) archipelagoes in the East Sea made its debut in Ho Chi Minh City on June 3 on the occasion of Vietnam’s Sea and Island Week.

The eight-chapter book presents the historic establishment and development of the nation’s islands in the past and at present.

It also introduces documents and ancient maps collected by geographers and historians of Vietnam and other countries, including China.

Researcher Nguyen Dinh Dau, the author of the book, said he has spent over 50 years collecting and studying more than 3,000 maps dating back 500 years, all of which demonstrate Vietnam’s sovereignty over Hoang Sa and Truong Sa archipelagoes.

Phan Thanh Binh, Director of the Ho Chi Minh City National University, said the analysis of these ancient documents, notes, maps, and nautical charts in the book will help reinforce the historical evidence confirming Vietnam’s sea and island sovereignty, which has been largely recognised by the international community.

An exhibition showcasing 93 maps of Nguyen Dinh Dau also opened in the city on June 3 as part of the Sea and Island Week. The event will run until June 8.

Vietnam has established and exercised its sovereignty over Hoang Sa and Truong Sa archipelagoes in a peaceful and continuous manner in line with international law at least since the 17th century.

According to Vietnam’s feudal state history, thousands of sailors overcame roaring waves and storms to survey sea routes, plant milestones and erect steles affirming national territory in Hoang Sa and Truong Sa archipelagos, and mined marine resources on the orders of the ruling Nguyen Lords. Their missions were full of dangers, and many of them never returned to land.-VNA
