Chinese Premier Li Keqiang has been received by the Queen on the first full day of his official visit to the UK.
Mr Li has also been holding talks with David Cameron in Downing Street.
It is the first UK visit by a Chinese premier since a row in 2012 over Mr Cameron’s meeting with exiled Tibetan spiritual leader, the Dalai Lama.
Mr Li has said he hopes the trip will help to “change misperceptions and misgivings” about his country as well as further business and cultural ties.
The UK has said it remains “deeply concerned” about human rights abuses in China.
High-level relations between the UK and China were frozen for a time after Mr Cameron’s meeting with the Dalai Lama but, after a change of leadership at the top of the Chinese Communist Party in March 2013, Mr Cameron visited the country in December.
