In 1930 the major tea producing areas of the time--India, Ceylon, and Java--together negotiated limits on tea production. As these restrictions went into place, Taiwan's tea industry seized its chance. Exports jumped to 3.29 million kilograms, and Oolong and Pouchong tea became popular.
1930 年世界紅茶主要生產國印度、錫蘭、爪哇相互協定限制生產，隨後又聯合限制輸出，讓台灣紅茶有竄起機會，出口量一躍達到 329 萬公斤，和烏龍茶、包種茶鼎足而立。
