UNDATED (CNN) -- The Chiang Mai Zoo in northern Thailand hosts a celebration for Lin Ping, the first Thai-born giant panda who has turned three years and nine months on Wednesday.
Born of the pair of pandas on loan from China, Xuang Xuang and Lin Hui, Thailand's sweetheart's age according to the zoo officials is equivalent to 14 years in human year.
She enjoyed sub-zero temperature and artificial snow inside the Zoo's snow dome and special treat which is an ice cake garnished with her favorite fruits. The panda now weighs 110 kilograms, only 10 kilograms less than Lin Hui.
Prasertsak Buntrakulpuntavee, head of the Zoo's panda research program, said Lin Ping now reached reproductive age however there was no plan to arrange a mating until she was six years old.
The current agreement with China allows Lin Ping to stay in Thailand until May this year but the Thai government is negotiation for a three-year extension. If agreed, Lin Ping will be the first panda to stay in a foreign country for more than four years.
There will be an opportunity for the zoo to put Lin Ping in mating attempt.
During last November's Thailand visit by Chinese premier Wen Jiabao, China agreed to consider extending the stay of female giant panda. The two sides are working to iron out the details of future agreement.
