2013年6月，中美两国元首在安纳伯格庄园会晤时一致同意致力于建立一种基于“务实合作”和“建设性管控分歧”的双边关系。务实合作与管控分歧成为引领两国关系发展的重要原则。在这一原则的引领下，2014年中美关系取得了许多积极或突破性进展：高层对话频繁，政治互信得到提升；经贸关系稳步发展，双边投资协定（BIT）谈判取得突破；气候变化合作取得突破；新型军事关系建设取得积极进展；在地区及全球层次上保持着密切安全合作。两国在经贸、人权、海洋争端、网络安全、美国对台军售、香港政制发展、新疆和西藏等领域的分歧基本得到妥善管控。所有这些为2015年中美关系平稳发展奠定了坚实基础。
During the Sunnylands Summit in June 2013，President Xi Jinping and President Obama agreed to build a bilateral relationship based on practical cooperation and constructive management of differences. Since then，deepening practical cooperation and constructively managing differences have become the key principle guiding the progress of Sino-US relationship. Guided by this principle，Sino-US relationship achieved many positive or groundbreaking progresses in 2014：frequent high level dialogues with the increase of political mutual trust；stable development of trade；breakthroughs on BIT negotiation；cooperation in acting on climate change；positive development in the building of New Type of Mil-to-Mil relations；and close security cooperation on regional and global levels. Meanwhile，the differences in areas such as trade，human rights，maritime disputes，cyber security，the U.S. selling weapons to Taiwan；political development in Hong Kong，and issues about Xinjiang and Tibet，were properly managed. All these have laid a strong foundation for the stable development of Sino-US relationship in 2015.
