The Customs Department in Da Nang City has fined a Chinese tourist VND30 million (US$1,423) for carrying maps which do not show Hoang Sa (Paracel) and Truong Sa (Spratly) archipelagoes as parts of Vietnam.
The department announced Tuesday that all the maps that Li Ye, 31, brought to Vietnam will be destroyed.
The woman was also forced to exit the country and was warned that she would face a heavier fine if she repeats her act in the future.
On October 23, Li had just arrived at Da Nang International Airport after flying from China's Guangzhou City when customs officers scanned her luggage and found 257 maps.
The maps of Da Nang include smaller maps of Vietnam on their right corner. But the maps of Vietnam do not have Vietnam's Hoang Sa and Truong Sa archipelagoes on them.
Li told customs officers she brought the maps to Vietnam to distribute them to other Chinese tourists.
According to the Da Nang Airport's customs officers, it is the fourth time this year they discovered Chinese tourists with maps, guidebooks and leaflets which do not portray the two archipelagoes as parts of Vietnam.
They said around 1,000 publications, all brought from Guangzhou, had been seized in such occasions.
This time, the fine for such violation has been raised from VND5-7 million to VND30 million.
