Bilateral trade between China and Tanzania has increased by almost 70%, climaxing at US$47million last year. According to the secretary of bilateral trade at the Chinese Embassy in Dar es Salaam, imports by China from Tanzania went up by 150.1% valued at $17million while exports from China to Tanzania increased by 40.6% to $3 million. The increase is attributed to the special preferential tariff (SPT) agreement-involving 190 tariff items-to the most undeveloped countries in Africa.
