Plans to build mainland China's first Disneyland park in Shanghai have yet to be given the go ahead by the central government, state media reported on Monday.

Walt Disney Co and Shanghai's government have agreed on major issues in building the park, the official Shanghai Securities News reported, while the US firm said in January it would be submitting a joint application to Beijing.

However, the paper, citing Liu Zhengyi, a vice head of Shanghai's Pudong district, said it had still not been given final approval. Disney officials were not immediately available for comment on Monday.

The company has been in talks with Chinese officials for a decade about building a large theme park and hotel complex in the southern part of the Pudong district in China's economic hub and largest city. No timetable has been given for the park, but previous reports had said officials hoped it could open as early as 2014.

Meanwhile, Disney has stepped up promotional campaigns for its Hong Kong resort with massive billboards inside Shanghai metro stations. State media has reported previously that Disney's Shanghai theme park could be eight times the size of its underperforming resort in Hong Kong, which is 52-percent government owned.
