This pro-Kremlin disinformation narrative is presenting Lithuania as a puppet of the US and provider of American interests in Europe.
The relations between the US and Lithuania are grounded on mutual respect and partnership. The US sees Lithuania as “a strong, effective partner committed to promoting democratic principles at home and abroad”.
The statement that the US want to influence the policy of Europe also is groundless. The United States and European states are independent and sovereign members of the international community. They are members of the United Nations of which Article 2 (4) of the Charter states that all Members must respect the sovereignty, territorial integrity and political independence of other States.
The US is an important ally to the EU but the later policy is not determined by the US, as explained by the EU High Representative. The US and the EU cooperate in areas ranging from agriculture to security, from foreign policy to the environment. This cooperation is appreciated by the parties.
The US also does not need Lithuania to put the "Chinese question" into the agenda of NATO or EU. As NATO member the US could raise actual questions for Alliance on its own.
The EU has its own agenda on China (see for example questions on EU-China relations).
