Aerial view of the Shanghai Disneyland Resort under construction in Pudong, Shanghai, China, 8 April 2015. Walt Disney Co will push back the opening of Shanghai Disneyland until the first half of 2016 from a scheduled start at the end of this year due to an expansion of its plans for the theme park, said a person familiar with the matter. Results from consumer studies and weather concerns had also played a part in the decision, said the person, adding that the change would likely be confirmed by the company. U.S.-based Walt Disney officials were not immediately available to comment. The $5.5 billion theme park is being jointly developed with China's state-owned Shanghai Shendi Group. In April, the firms said they would increase investment in the theme park by $800 million, which would be used primarily to fund additional attractions.
