I don’t think you’re going to find a smoking gun here, but there are plenty of signs and also a larger pattern in the region for this sort of thing. This is from a great Vijay Prishad article posted elsewhere here:

Over the course of the past decade, South Asia has faced significant challenges as the United States imposed a new cold war against China. Initially, India participated with the United States in the formations around the US Indo-Pacific Strategy. But, since the Russian invasion of Ukraine in February 2022, India has begun to distance itself from this US initiative and tried to put its own national agenda at the forefront. This meant that India did not condemn Russia but continued to buy Russian oil. At the same time, China had—through the Belt and Road Initiative (BRI)—built infrastructure in Bangladesh, Nepal, Pakistan, and Sri Lanka, India’s neighbors.

It is perhaps not a coincidence that four governments in the region that had begun to collaborate with the BRI have fallen, and that their replacements in three of them are eager for better ties with the United States. This includes Shehbaz Sharif, who came to power in Pakistan in April 2022 with the ouster of Imran Khan (now in prison), Ranil Wickremesinghe, who briefly came to power in Sri Lanka in July 2022 after setting aside a mass uprising that had other ideas than the installation of a party with only one member in parliament (Wickremesinghe himself), and KP Sharma Oli, who came to power in July 2024 in Nepal after a parliamentary shuffle that removed the Maoists from power.
