Chinese President Xi Jinping (centre R wearing red tie) sings a song entitled "My Country" with performers of a variety show along with outgoing chief executive Leung Chun-ying (centre L) and incoming leader Carrie Lam (centre R) during his visit to Hong Kong on June 30, 2017. In the midst of celebrations marking 20 years since Britain returned Hong Kong to China, Beijing declared that the document which initiated the handover "is no longer relevant." The remarks on June 30 came a day after UK Foreign Minister Boris Johnson stressed Britain's commitment to the historic Sino-Britain Joint Declaration, which gave Hong Kong rights unseen on the mainland through a "one country, two systems" agreement. / AFP PHOTO / Anthony WALLACE (Photo credit should read ANTHONY WALLACE/AFP/Getty Images)
