Holland's Queen Maxima has cut short a state visit to China due to illness.
The 44-year-old royal was visiting China with her husband, King Willem-Alexander, when she developed a fever and back pain, which has been diagnosed as a kidney infection, the Dutch Royal House announced.
Queen Maxima will be admitted to Bronovo Hospital in The Hague for further testing and treatment when she arrives home.
Her husband Willem-Alexander will stay on in China and complete his itinerary with Chinese officials.
After the news was announced, King Willem-Alexander tweeted: "Many thanks for all the wishes for a speedy recovery. I will pass them on to my wife."
The king and queen were accompanied on the trip by 150-strong Dutch trade mission - the second largest Dutch trade mission ever.
Foreign minister Bert Koenders, who is leading the delegation, has assured critics that human rights will be raised with the Chinese authorities during the visit.
Willem-Alexander became king in 2013 after the abdication of his mother, Queen Beatrix and the couple have three daughters together.
