Tanzania and China have signed investment deals worth more than $1.7bn, including one to build a satellite city to ease congestion in the commercial capital Dar es Salaam – deepening Beijing’s ties with East Africa.

The money will be used to develop infrastructure, power distribution and business co-operation, Tanzanian President Jakaya Kikwete said in a statement yesterday, a day after the deals were formally signed in Beijing.

Tanzania later announced a $85mn in grants and zero-interest loans from China. It did not say what the money would be used for.

The deals extend China’s growing economic presence in Tanzania, which has made major natural gas discoveries off its southern coast.

The satellite city, on the outskirts of Dar es Salaam, will be a self-contained urban zone equipped with water, electricity, roads, banks, schools and hospitals.

The project, as well as a $500mn financial centre that will also be built in Dar es Salaam, are joint projects by the China Railway Jianchang Engineering Company (CRJE) and Tanzania’s state-run National Housing Corporation.

Tanzania’s state-run power company, TANESCO, meanwhile signed a deal with China’s TBEA Hengyang Transformer Co. for a rural electrification project that Kikwete’s office said would be worth “millions of dollars”. It did not elaborate.

In recent years, Chinese companies have signed deals to build a rail network and a 532 km (330 mile) natural gas pipeline. Between July and September of this year, Chinese investments totalled $534mn, compared to $124mn during the same period last year.

China says it will “speed up the construction” of the Bagamoyo port, a new Indian Ocean project being built north of Dar es Salaam, and begin offshore oil and gas exploration off Tanzania, according to a statement issued by Kikwete’s office.

Speaking at an investment forum in Beijing this week, Kikwete said he hoped to boost Tanzania’s exports to the Asian powerhouse.

China’s exports to Tanzania, which totalled $1.099bn from 2012 to 2013, were roughly double the $495.74mn worth of goods China imported from Tanzania, he said.

“It’s obvious we can do better,” he said.
