Original sentence: Although Goguryeo paid China for diplomatic and trading reasons during peacetime, Goguryeo was not a tributary state.China claims that Goguryeo was a tributary state since Goguryeo engaged in this relationship however Goguryeo was not a true tributary state since China had no control over the Goguryeo government.Chinese historians disagree with this however.Most historians believe that Goguryeo ended its tributary status with China in 106 AD
