One of the key questions to me is how much of these increased exports were because of market growth and how much was down to rising prices and weak sterling.
Un o'r cwestiynau allweddol i mi yw faint o'r lefelau uwch hyn o allforion a mewnforion oedd oherwydd twf y farchnad a faint oedd i lawr i brisiau uwch a sterling gwan.
