TUNIS- Tunisia's trade deficit widened 23 percent year on year in the first nine months to 11.480 billion dinars, the State Statistics Institute said on Thursday.

The growing deficit is one of the main problems facing the government of Prime Minister Youssef Chahed.

It has contributed to an erosion of Tunisia's foreign currency reserves, which sank to just 90 days of imports in July, the weakest in three decades.

The deficit with China alone reached 3.241 billion dinars.

In an attempt to curb the deficit, Tunisia in April imposed restrictions on imports of some goods.
