The Thai economy has weathered internal and external economic shocks in recent years. The global economic recession severely cut Thailand's exports, with most sectors experiencing double-digit drops. In late 2011 Thailand's recovery was interrupted by historic flooding in the industrial areas in Bangkok and its five surrounding provinces, crippling the manufacturing sector. The government approved flood mitigation projects worth $11.7 billion, which were started in 2012, to prevent similar economic damage, and an additional $75 billion for infrastructure over the following seven years. This was expected to lead to an economic upsurge but growth has remained slow, in part due to ongoing political unrest and resulting uncertainties. Spending on infrastructure will require re-approval once a new government is seated.
