a few weeks later. The pandas gifted to the UK would later be the inspiration for the logo of the World Wildlife Fund. Lease policy In 1984, China's leader Deng Xiaoping modified the policy, such that subsequent pandas would be leased, instead of gifted, beginning with China presenting two pandas to Los Angeles during the 1984 Olympic Games for $50,000 per month per panda. This practice was again modified in 1991 in favor of long-term leases. China began to offer pandas to other nations only on ten-year lease. The standard lease terms include a fee of up to US$1 million per year and a provision that any cubs born during the lease period be the property of the People's Republic of China. Since 1998, because of a World Wildlife Fund lawsuit, the U.S. Fish and Wildlife Service allows a U.S. Zoo to import a panda only if the zoo can ensure that China will channel more than half of its loan fee into conservation efforts for wild pandas and their habitat. The gifting of two pandas to Hong Kong in 2007 was ostensibly an exception to this lease model, but can be seen as outside of the spectrum of panda diplomacy. After the 2008 Sichuan earthquake that severely damaged many facilities, 60 pandas required new housing. The majority were given to nations that had favorable trade agreements with China, or those that supplied China with necessary resources, such as uranium from Australia. International recognition Other countries recognize the significance of pandas as diplomatic symbols, emblematic of the state of relations with China. During a visit by then Chinese Leader Hu Jintao to Japan in May 2008, China announced the lease of two pandas to Japan. The leader was quoted as saying "Giant pandas are very popular among the Japanese, and they are a symbol of the friendly ties between Japan and China." Treatment of the pandas is likewise associated with the relevant foreign policy. For example, in 1964, British diplomats worried that a transfer of a panda from a London Zoo to Moscow would worsen Sino–Soviet relations. In January 2006, U.S. Deputy Secretary of State Robert Zoellick was photographed hugging a five-month-old panda cub during his visit to Sichuan. The image was widely broadcast by the Chinese media and was purportedly interpreted as a sign that Zoellick supported better relations between China and the United States. On April 16, 2014,
