On the 2015 international market，the dollar appreciates sharply，and the commodity prices decline simultaneously，resulting in the bizarre downward trend of world economy and trade. In recent years，the growth rate of China’s foreign trade has always been running low，and has even “ dived below the surface” during the year 2015，which has puzzled many people. It can be surmised that China’s foreign trade is in fact fluctuating in a reasonable range and in a normal orbit. The growth rate of China’s foreign trade shows a rare decrease in both exports（a decrease of 3.5%）and imports（a decrease of 16.5%），which is just a superficial phenomenon. There is more and more probability of a decline in the world economy in 2016，while China’s foreign trade is expected to dive downward. It is suggested that the government should implement a proactive reform policy and the central bank should implement a loose monetary policy. Since China possesses ample time to set policies，it should deal calmly and give priority to lifting the financial restrictions on private enterprises. If a new recession in the world’s economy occurs in 2016，China’s foreign trade will drop substantially；if it is weak，dollar-denominated exports will decline slightly and imports will decrease moderately.
