President Donald Trump proposed working with India and Pakistan to achieve a "solution" for the long-standing Kashmir region, and a few days later his administration established a ceasefire between two nuclear weapons rivals.

Trump posted on Sunday's truth social platform: "I'll work with you to see if it's possible to come up with a solution in Kashmir after 'million years'."

The U.S. president historically inaccurately asserts that India and Pakistan have been fighting for "a thousand years" or more.

Muslim majority territory has been competing since Britain India allocated to India and Pakistan in 1947. The two countries fought three wars in the region. Both of them have argued for the whole of Kashmir, but controls a part of it.

Indian-managed Kashmir has seen decades of armed insurgency, both independence and merger with Pakistan. New Delhi has deployed 700,000 soldiers to dismiss the rebellion.

To date, the government of Prime Minister Narendra Modi has been committed to rejecting decades of policy of international mediation to find solutions to Kashmir's problem. In 2019, the Modi government further alienated Kashmir by depriving the Indian-managed semi-automatic learning of Kashmir.

In a response, Pakistan's Foreign Ministry said in a statement on Sunday that it thanked Trump for his willingness to resolve the Kashmir issue, which had implications for peace and security in South Asia and beyond.

"Pakistan reiterates that any fair and lasting settlement of the Jamu and Kashmir dispute must comply with the resolutions of the relevant UN Security Council and that the fundamental rights of the Kashmiris, including their inalienable right to self-determination, must be ensured," it said.

India's leaders have not commented directly, but Indian media quoted unnamed government sources as saying that it has not yet decided to negotiate anything other than the ceasefire.

India and Pakistan agreed to stop all fights on Saturday, but Trump was the first to announce the deal on its online platform.

In Sunday's post, Trump praised for the ceasefire.

“I am proud of America being able to help you make this historic and heroic decision,” he wrote.

“Although there is no even discussion, I will greatly increase trade with these two great countries.”

The latest battle between the two neighbors began with the Indian-managed shootings attacking Pahalgam in Kashmir, Pakistan, who killed 26 civilians at the tourist location.

New Delhi has once again accused Pakistan of supporting “terrorist” groups that have carried out many deadly attacks in India-run Kashmir for decades.

Pakistan strongly denied the allegations, insisting that India has supported “terrorism” on its territory for many years and that the Pahargam attack was a false action to launch a war.

Since becoming a nuclear-weapon power decades ago, missiles, drones and artillery shells have attacked the worst battle between the two countries.

Negotiable websites for negotiation

U.S. Secretary of State Marco Rubio said on Saturday that in addition to the ceasefire, the two countries agreed to soon conduct extensive negotiations on many issues on the "neutral" site.

Pakistani Prime Minister Shehbaz Sharif said on Saturday that his country believes in the path to peace talks to address issues regarding water allocation and “all issues including Jamu and Kashmir”.

But for decades, India has refused to negotiate on disputed areas as it tries to strengthen its holdings of it.

Mohmad Waseem Malla, a researcher at the International Peace Research Centre in New Delhi, told Al Jazeera that Trump’s statement, while not entirely surprising, had “the tone and substance” and was likely to raise concerns in New Delhi.

“Any advice on third-party participation, even in passing, puts a red line on New Delhi, especially under the current government, which redefined the country’s foreign policy and its emphasis on territorial sovereignty.”

He added that while Trump’s reference to promoting trade and promoting peace appears to be reconciliation internationally, India’s domestic political climate and strategic focus make it difficult to enjoy such a offer now.

“The key will be how New Delhi calibrates its response in the current sensitivity situation.”

As India suspends its participation in the Indian Water Treaty ongoing existence, the two countries have not yet addressed their differences in water allocation.

In response to the Pahalgam attack, India also expelled Pakistani diplomats, military advisers and visa holders. Its main land border transit was closed and trade was suspended; and a pursuit was initiated for the perpetrators.

Pakistan's response was to kick out Indian officials and citizens, shut their space down flights to India, and threaten to withdraw from the Simla agreement, which underpins Kashmir's line of control.
