In 2013 Council agreed to establish a Sister Cities Advisory Group to facilitate the development of Sister City relationships in countries where the City of Karratha has relevant economic and cultural ties.
The Advisory Group recommended that China be the priority for a Sister City relationship. Following a delegation in February 2014, Lanshan District, Rizhao was selected the preferred Sister City candidate from China.
In August 2014 a delegation representing Council, business, education and indigenous organisations travelled to Rizhao, Qingdao and Shanghai to further develop the relationship with Lanshan District, establish contacts to enable cultural and educational exchanges for teachers and students and to meet with key investors from China.
In November 2014 Mayor Zhang Guiwei of the Lanshan District of Rizhao, China and Mayor Peter Long of the City of Karratha officially signed a Sister City agreement to focus on trade, education and the promotion of cultural links.
