Most of these treasures are owned by museums or private collectors in the United States，Japan，some European countries and Southeast Asian countries.There are more than 23，000 pieces in the British Museum，most of which were stolen or bought for pennies more than 100 years ago. The major method of recovering these national treasures is to buy them back.In some cases，private collectors donated the relics to the government.Also the government can turn to official channels（渠道）to demand the return of the relics. In 2003，a priceless bronze pig head dating from the Qing Dynasty was returned to its home in Beijing after it was removed by the Anglo-French Allied Forces over 140 years ago.Stanley Ho donated 6 million yuan to buy it back from a US art collector and then donated it to the Poly Art Museum in Beijing. Although buying-back is the most feasible way to recover the lost treasures，limited funding is always a big headache. In recent years， the Chinese government has put more effort into recovering the precious cultural relics lost overseas. It has started a national project on the recovery of the treasures and has set up a database collecting relevant information. It has signed several international agreements with many countries on this matter，and is also looking for international cooperation to recover the relics by working closely with several international organizations.（1）What is the passage mainly about？ ____
