Chinese President Xi Jinping sent a congratulatory letter to a commemorative event marking the 50th anniversary of cooperation between China and the World Intellectual Property Organization (WIPO) on Wednesday.

Xi noted that, over the past 50 years, China has been firmly committed to upholding the multilateral system of international intellectual property rights (IPR), and the country's cooperation with the WIPO has been expanded and deepened with fruitful results.

China has always attached great importance to IPR protection, and exerted efforts to make the country strong in intellectual property. China has strengthened the legal protection of IPR, improved the IPR management system, strengthened IPR full-chain protection, and continued to improve the innovation and business environment, Xi stressed in the letter.

China is willing to further deepen the friendly cooperation with the WIPO, and work together to make the global intellectual property governance system fairer and more equitable and better improve the well-being of humankind, said Xi.

The commemorative event was held in Beijing on Wednesday.
