Chinese President Xi Jinping has arrived in California for summit talks with US President Barack Obama, BBC News reported.

The two-day meeting, at a private estate, is the first between the two since Xi became president in March. The informal setting is seen as a chance for the leaders of the world's largest economies to build a rapport amid a slew of high-stakes issues. Cyber espionage is expected to top the agenda, with North Korea, Asian security and trade also key topics. US lawmakers and human rights groups have also urged Obama to call for the release of 16 high-profile prisoners, including jailed Nobel peace laureate Liu Xiaobo. Xi's US stop is the fourth leg of a trip that has taken him to Trinidad and Tobago, Costa Rica and Mexico. Accompanied by his wife, folk singer Peng Liyuan, he arrived at California's Ontario International Airport on Thursday, June 6.
