Meanwhile, in Viet Nam, fruits and vegetables seem to adjust less quickly than computers and electrical products. This indicates that the speed of adjustment tends to vary by commodity and by country, which is presumably determined by the macroeconomic structure, extent of global value chain involvement of each sector in the economy, free trade agreements and investment linkages, among other factors. The dip in exports of electrical machinery began more recently and less pronouncedly than that of edible vegetables, though in both cases the weakness appears to be persistent. In the case of Viet Nam, the trend of declining growth in fruit and vegetable exports to China also began earlier than that of computers and electronics, which started to edge lower late in 2018, although both categories appear to be recovering in 2019. The speed of upward adjustment of exports this good to other markets is substantially slower than the downward adjustment of exports to China.
