As of July 31, 2018, debt held by the public was $15.6 trillion and intragovernmental holdings were $5.7 trillion, for a total or ``National Debt ''of $21.3 trillion. Debt held by the public was approximately 77% of GDP in 2017, ranked 43rd highest out of 207 countries. As of December 2017, $6.3 trillion or approximately 45% of the debt held by the public was owned by foreign investors, the largest being China (about $1.18 trillion) then Japan (about $1.06 trillion). The Congressional Budget Office forecast in April 2018 that the ratio will rise to nearly 100% by 2028, perhaps higher if current policies are extended beyond their scheduled expiration date. <SEP> Party and government leaders Name Position (s) in 1989 Deng Xiaoping Chairman of the Central Military Commission; de facto ``paramount leader ''Chen Yun Chairman of the CPC Central Advisory Commission Zhao Ziyang General Secretary of the Communist Party of China First Vice-Chairman of the Central Military Commission Li Peng Premier of the People's Republic of China Qiao Shi Secretary of the CPC Central Commission for Discipline Inspection Secretary of the CPC Political and Legislative Affairs Committee Hu Qili First Secretary of the Secretariat of the Communist Party Yao Yilin First Vice Premier of the People's Republic of China Yang Shangkun President of the People's Republic of China Vice-Chairman of the Central Military Commission Li Xiannian Chairman of the Conference National Committee Wan Li Chairman of the Congress Standing Committee Wang Zhen Vice President of the People's Republic of China Jiang Zemin Communist Party Shanghai Municipal Secretary Li Ximing Communist Party Beijing Municipal Secretary Zhu Rongji Mayor of Shanghai Chen Xitong Mayor of Beijing Hu Jintao Communist Party Tibet Regional Secretary Wen Jiabao Chief of the General Office of the Communist Party of China Bold text indicates membership in the Politburo Standing Committee Italics text indicates Great Eminent Officials <SEP> Zhuo Lin (April 6, 1916 – July 29, 2009) was the third and last wife of Deng Xiaoping, former Paramount leader of China. <SEP> the 2010 nobel peace prize was awarded to imprisoned chinese human rights activist liu xiaobo ``for his long and non-violent struggle for fundamental human rights in china ''. the laureate, once an eminent scholar, was reportedly little - known inside the people's republic of china (prc) at the time of the award due to official censorship; he partook in the tiananmen square protests of 1989 and was a co-author of the charter 08 manifesto, for which he was sentenced to 11 years in prison on 25 december 2009. liu, who was backed by former czech president václav havel and anti-apartheid activist and cleric desmond tutu, also a nobel peace prize winner, received the award among a record field of more than 200 nominees. <SEP> the events of the full - blown revolution began in poland in 1989 and continued in hungary, east germany, bulgaria, czechoslovakia and romania. one feature common to most of these developments was the extensive use of campaigns of civil resistance, demonstrating popular opposition to the continuation of one - party rule and contributing to the pressure for change. romania was the only eastern bloc country whose people overthrew its communist regime violently. protests in tiananmen square (april to june 1989) failed to stimulate major political changes in china, but influential images of courageous defiance during that protest helped to precipitate events in other parts of the globe. on 4 june 1989 the trade union solidarity won an overwhelming victory in a partially free election in poland, leading to the peaceful fall of communism in that country in the summer of 1989. hungary began (june 1989) dismantling its section of the physical iron curtain, leading to a exodus of east germans through hungary, which destabilised east germany. this led to mass demonstrations in cities such as leipzig and subsequently to the fall of the berlin wall in november 1989, which served as the symbolic gateway to german reunification in 1990.
