On May 1, 1919, British Foreign Secretary Balfour summoned Shi Zhaoji and Gu Weijun to inform them of the decision of the Paris Conference on the Shandong issue. Balfour said: "When investigating the Shandong issue, the resolution methods are generally at two ends. Political power will be returned to China and economic power will be given to Japan. I believe China will be satisfied. "On the same day, the China delegation lodged a strong protest to the Paris Conference. On May 6, Lu Zhengxiang and Wang Zhengting attended the Entente Conference. After seeing the full text of the Peace Treaty with Germany, Lu Zhengxiang immediately spoke in protest: "The China delegation has to express its deep disappointment with the measures proposed at the Paris Conference on Jiaozhou and Shandong issues. "The representative of China formally expressed reservations to the Shandong Clause. On May 7, the draft treaty on the peace treaty with Germany was delivered to the German representative, allowing the German side to request and explain the draft treaty within 15 days. In response, Lu Zhengxiang called the government and said: The various circumstances and methods of this peace meeting are indeed resentful. There is still a 15-day deadline for enemy countries, so we are allowed to ask questions about their doubts. However, we are not willing to disclose our country's secrets before finalizing the final version. There is no time for discussion after the final version. This is really commendable for our situation.
