The recent trade dispute between Japan and China over three farm products was a harbinger of future trade friction between the two countries, according to pundits.

Both countries agreed on Friday to end the dispute that erupted in April when Japan launched provisional import curbs on three agricultural products -- stone leeks, shiitake mushrooms and rushes used for tatami -- that come mainly from China.

In June, China retaliated by imposing special import duties on automobiles, air conditioners and mobile phones from Japan.
