Yin Hong, deputy director of the State Forestry Administration, said on Monday that endangered animals can be saved if nations work together.

"The conservation of tigers and combating illegal trade in wildlife require the concerted effort of all the nations where they live," she said.

There are 13 tiger range countries, and they differ in their abilities in funding, law enforcement, supervision and scientific know-how.

Yin said more help should be made available to countries with weaker financial capabilities, law enforcement and scientific development.

The 13 countries created Global Tiger Day at the Tiger Summit in November 2010 in St Petersburg, Russia. The day is celebrated annually on July 29 to raise awareness of support for the conservation of wild tigers.

There are 3,200 to 3,500 wild tigers in the world, and the 13 nations have agreed to increase their number to 6,000 by 2022.

"We have set an ambitious goal," said Mike Baltzer, head of the WWF Tigers Alive Initiative. "To know global tiger population numbers will be to know where we are and will help understand what else we need to do together to put tigers in a safe place by 2022."

He said that determining the exact number of tigers in the wild is difficult because they are notoriously elusive and inhabit often remote and rugged terrain. Jiang Guangshun, of the China State Forestry Administration's Feline Research Center, said international cooperation is needed to count the tiger population.

For many countries, finding the number of tigers has been prohibitively expensive and time-consuming because many lack the techniques and equipment to survey tigers, particularly cheaper and more durable camera traps.

Jiang said China built a tiger/leopard monitoring platform in 2011 to collect information on the big cats' ranges and DNA as well as footprint images to create a database.
