China and Mexico established diplomatic relations. In 1973, Mexican President Luis Echeverría paid an official visit to China and met with Chinese Communist Party chairman Mao Zedong. In 2005, Chinese leader Hu Jintao came to Mexico promising increased investment in industries like automobile-parts manufacture and mineral exportation. In July 2008, Mexican President Felipe Calderón reciprocated with a visit to Beijing in a bid to improve bilateral trade. Nevertheless, China has focused more on South American commodity producers such as Brazil and Chile to meet this end and fuel its chiefly-export economy. In 2008, Mexico exported just $2 billion worth of goods to China while importing some $34 billion from them, including clothing, electronics and "tourist trinkets". 2009 swine flu dispute In 2009, in the wake of fears of a worldwide swine flu pandemic, thought to have started in Mexico, relations between the two countries cooled substantially over China's decision to quarantine some seventy Mexican citizens, despite none of them showing symptoms of the virus.
