The 20th Party Congress opened in Beijing on Sunday, October 16. Xi Jinping delivered the report to the Congress on behalf of the 19th Central Committee. You can find the Chinese and English versions of the full report below.

Three things to note. First, the report and translation below, while from official sources, have not been publically released. The reason is that the report and an English translation will only be officially published at the end of the Congress (on October 22). That version will not be different from the version below in any material way.

Second, the normal practice is for the General Secretary to read the report to Congress in its entirety. At the 19th Party Congress, it took Xi three hours to read the report. This time, Xi only read a truncated version of the report. The reason for that is unclear but possibly related to Xi's health condition.

Third, if you need a crash course on the report, see Holly Snape's guide:

Hold High the Great Banner of Socialism with Chinese  Characteristics and Strive in Unity to Build a Modern Socialist Country in All Respects

Report to the 20th National Congress of the Communist Party of China
October 16, 2022

Xi Jinping

Comrades,
  On behalf of the 19th Central Committee of the Communist Party of  China (CPC), I will now deliver a report to the 20th National Congress.  The 20th National Congress of the Communist Party of China is a meeting of great importance. It takes place at a critical time as the entire Party and the Chinese people of all ethnic groups embark on a new journey to build China into a modern socialist country in all respects and advance toward the Second Centenary Goal.
  The theme of this Congress is holding high the great banner of socialism with Chinese characteristics, fully implementing the Thought on Socialism with Chinese Characteristics for a New Era, carrying forward the great founding spirit of the Party, staying confident and building strength,  upholding fundamental principles and breaking new ground, forging ahead with enterprise and fortitude, and striving in unity to build a modern socialist country in all respects and advance the great rejuvenation of the  Chinese nation on all fronts.
  Since its founding a century ago, the Communist Party of China has taken a remarkable journey. Our Party has dedicated itself to achieving lasting greatness for the Chinese nation and committed itself to the noble cause of peace and development for humanity. Our responsibility is unmatched in importance, and our mission is glorious beyond compare. It is imperative that all of us in the Party never forget our original aspiration and founding mission, that we always stay modest, prudent, and hard-working, and that we have the courage and ability to carry on our fight. We must remain confident in our history, exhibit greater historical initiative, and write an even more magnificent chapter for socialism with Chinese characteristics in the new era.
