2019年，马来西亚执政的希望联盟发生内讧，政治斗争加剧，民众对希望联盟的不满情绪增加。马哈蒂尔总理与人民公正党主席安瓦尔之间的权力交接问题受到普遍关注，二人关系微妙、复杂、多变。政府出台了新外交政策框架和国防白皮书，务实推进对华、对东南亚外交和国防建设，应对恐怖主义、疾病灾害等安全威胁。但全年经济发展下行压力加大，马来民族主义情绪上升，族群矛盾加剧，国家治理困难凸显。2020年2月，马哈蒂尔突然辞职下台，使其与安瓦尔之间的权力交接问题画上句号。3月1日，土著团结党主席穆希丁被最高元首任命为第八届政府总理，引发新一轮政治博弈。
The year of 2019 witnessed intense political struggle in Pakatan Harapan，the ruling coalition in Malaysia. People’s dissatisfaction with the Pakatan Harapan-led government increased. Whether Tun Dr. Mahathir，the Prime Minister of Malaysia will hand over his power to Anwar Ibrahim，the President of Parti Keadilan Rakyat，drew great attention. Though the government published its new foreign policy framework and the first National Defence White Paper to promote the relations with neighboring countries and enhance defense capabilities，the economy encountered great pressure for sustainable growth and the contradiction among ethnic groups intensified. In February 2020，Tun Dr. Mahathir stepped down unexpectedly in order to seek for the power again by the support of the newly political party alliance called Perikatan Nasional. However，Tan Sri Muhyiddin Yassin，the President of Parti Pribumi Bersatu Malaysia，was finally appointed to become the new Prime Minister，making the situation full of uncertainties.
