About a dozen Chinese companies have expressed their interest to invest in the development of the industrial zone in Tanah Kuning, North Kalimantan. For example, Chen Zemin, General Director of Zhengzhou Demeter New Energy Technology Co Ltd, said the company is interested to invest in the North Kalimantan industrial zone and will send a delegation to inspect the zone within three months. Other Chinese companies interested to invest in this industrial estate are MEHEO and China Power International Development Ltd. The industrial zone in Tanah Kuning (North Kalimantan) will be developed on a 11,000 hectares plot of land. It will focus on the bauxite and aluminum processing industry. However, the area will also need additional infrastructure such as an international harbor. It therefore requires US$1.5 billion worth of investment.
