CP Pokphand shares extended their dramatic decline yesterday as the firm said that talks were still under way with creditors over debt restructuring. The Hong Kong arm of the leading Thai conglomerate saw its share price plunge 27.5 per cent to finish at 50 cents. The stock has dropped 56.5 per cent in the past four trading sessions.

According to analysts, the firm has estimated foreign currency debts of more than $1 billion.
