After Shanghai became the first city allowed by the State Council to build a free trade zone last week, other cities are ready to follow suit.

Tianjin filed its proposal to the central government, while the city government of Xiamen, Fujian province, is collecting documents to submit to the State Council for approval.

While Tianjin's plan might be approved in a month by the State Council, according to a 21st Century Business Herald report on Wednesday, Xiamen's plan is still being drafted, and no details about the time frame or the zone have been decided yet, said an official surnamed Xu with the Xiamen investment promotion bureau.
