The first cargo plane transporting the narcotic leaf known as khat has arrived in Somalia from Kenya, following a two-year ban due to a souring of diplomatic relations.
The trade is worth tens of millions of dollars a year.
Earlier this month President Uhuru Kenyatta and his Somali counterpart Hassan Sheikh Mohamud signed an agreement which will also see a resumption of trade in fish.
Somalia imposed a ban on the leaf ,also known as miraa, after accusing Kenya of meddling in the country's politics and due to a maritime border dispute.
President Mohamud's election victory in May led to a thawing of relations.
