China said on Monday the United States was "addicted to quitting" following a US decision to leave the World Health Organization (WHO) and said the withdrawal reveals a pursuit of power politics and unilateralism.
Foreign ministry spokesman Zhao Lijian told reporters during a daily briefing that the international community disagreed with what he described as the selfish behaviour of the United States.
"The US has become addicted to quitting groups and scrapping treaties," said Zhao.
President Donald Trump announced on Friday the United States would cut ties with the WHO, accusing the UN agency of becoming a puppet of China.
The WHO has denied Trump's assertions that it promoted Chinese "disinformation" about the novel coronavirus, which emerged in China late last year.
Trump's decision follows a May 18 pledge of $2 billion by Chinese President Xi Jinping at the World Health Assembly - the WHO decision-making body - to help deal with the coronavirus and economic and social development in affected countries, especially developing countries. It was not immediately clear how much of that money would actually go to the WHO.
The EU on Saturday urged the United States to reconsider its decision.
China calls on the international community to provide more political support and funding for the WHO, said Zhao.
The US decision to quit the Geneva-based agency comes amid growing tension between the United States and China over the coronavirus outbreak.
Since taking office, Trump has questioned the value of the United Nations and scorned the importance of multilateralism as he focuses on an "America First" agenda.
He has quit the U.N. Human Rights Council, the UN cultural agency UNESCO, a global accord to tackle climate change, the Iran nuclear deal and opposed a U.N. migration pact.
