Imports to South Sudan through Kenya’s main port have fallen to the lowest-ever level as resurgent violence in the world’s youngest nation hurt the fledgling economy and sent traders and citizens fleeing.

Only 525 twenty-foot equivalent units of cargo were cleared at the Mombasa port in July, compared with a monthly average of 4,000 TEUs in 2013, just before the nation descended into fresh fighting, according to Ayuel Mathach Deng, the government’s representative at the Indian Ocean port city.
