Alibaba Group has obtained a preliminary injunction from a US federal court, blocking a rule that restricted Pentagon contracts for companies doing business with firms lobbying on its behalf. The decision, issued by Judge Eumi K. Lee, prevents the government from enforcing the restriction, which had led to the departure of Alibaba’s Washington-based lobbyists.

The court ruled that the government had not provided sufficient evidence to justify the restriction, which effectively forced lobbying firms to choose between representing Alibaba and clients seeking Pentagon contracts. The injunction allows Alibaba to continue its lobbying efforts without facing potential exclusion from defense contracts.

The restriction, introduced by the US Department of Defense, aimed to limit influence from foreign entities, particularly those with ties to Chinese technology firms. Alibaba challenged the rule, arguing it violated free-speech protections under the First Amendment. The case highlights ongoing tensions between US defense policies and foreign business interests, particularly those linked to China. The ruling is a significant legal victory for Alibaba, reinforcing its position in the US political and business landscape.
