Exhibit 99.1

Xinyuan Real Estate Co., Ltd. Announces Delayed Filing of Annual Report on Form 20-F

Beijing, May 17, 2022 -- Xinyuan Real Estate Co., Ltd. (“Xinyuan” or the “Company”) (NYSE: XIN), an NYSE-listed real estate developer operating primarily in China and also in other countries, announces that its annual report on Form 20-F for the year ended December 31, 2021 (the “Annual Report”) cannot be filed within the 15-day extension period under Rule 12b-25(b)(2)(ii) under the Securities Exchange Act of 1934.

The delayed filing is because the Company’s independent auditor requires additional time to complete its audit of the financial statements for the Annual Report. The independent auditor has had less time than it typically would have to complete the audit because of the Company’s delayed filing of its annual report for 2020 on Form 20-F which it filed on March 8, 2022.

The independent auditor has been working diligently on the audit and has only a few procedures outstanding to complete, which include the on-site audit of the Company’s significant investments and obtaining of certain banks’ confirmation letters. These procedures have been disrupted by the strict quarantine measures put in place by the Shanghai Municipal Government as a result of the COVID-19 resurgence in Shanghai in late March and early April 2022, which affects the majority of the independent auditor’s workforce.

The Company expects to file the Annual Report within two months once the strict quarantine measures in Shanghai are lifted. The Company cannot predict when that will occur.
