Malaysia joined India on Wednesday in protesting against a new Chinese map which claims India’s territorial areas and Malaysia’s maritime area near Borneo Island ahead of the Group of 20 summit next week in New Delhi.

The tensions between China, India and Pakistan have been heightened by this. They are involved in a three year military standoff on their shared border.

It is important to time the protest, because Chinese President Xi Jinping will be attending the summit.

“We reject these allegations as they are without basis. “Such steps by the Chinese only complicate the solution of the boundary issue,” India’s External Affairs Ministry spokesperson Arindam Bagchi stated in a late Tuesday statement.

Malaysia’s Foreign Ministry in a Wednesday statement rejected China’s unilateral claims and added that the map was “not binding”.

The document also called for a rational and peaceful resolution of the conflict through dialogue and negotiation.

India has lodged a formal objection to the Chinese government on the “standard map 2023” which claims Indian territory.

The Chinese map, published on Monday by the Ministry of Natural Resources, clearly shows Arunachal and Doklam Plateau in the western part of China that India claims, as well as Aksai-Chin, within the Chinese border.

In a TV interview that aired on Tuesday, the Indian Minister of External Affairs Jaishankar Subhramanyam dismissed China’s claims.

We are clear about our territory. It should not be in doubt. “Making absurd claims does not make someone else’s land yours,” said he.

China refused to remove visas from the passports Arunachal Pradesh officials in northeast India, instead using a certificate stapled into the passport, which implied the Chinese claim over the territory.

It refuses to acknowledge India’s sovereignty in the part of Kashmir that it controls, and has refused to send a delegates to a G20 summit there in May.

On the sidelines of the BRICS Summit in Johannesburg last week, Indian Premier Narendra Modi spoke informally to China’s president Xi. The premier brought up New Delhi’s concerns over their unresolved borders issues.

The Indian Foreign Ministry said that the two leaders had agreed to intensify their efforts to deescalate tensions along the disputed border, and to bring back thousands of troops stationed there.

Tens of thousands Indian and Chinese soldiers have been locked in a standoff for three years over the disputed border. In a clash that occurred in the area three years ago, 20 Indian soldiers were killed and four Chinese.

The Chinese Foreign Ministry stated that the two sides must consider the general interests of their bilateral relationships and properly handle the border issue in order to safeguard the peace and tranquility along the border.

In an apparent attempt to stabilize the situation, Indian and Chinese military leaders met earlier this month.

A “line of actual control” separates Chinese- and Indian-held territory from Ladakh, in the west, to Arunachal Pradesh in India’s east, which China claims as its entire state.

In 1962, India and China fought over their border. China claims 90,000 square kilometers of territory in India’s northeast including Arunachal Pradesh, which has a predominantly Buddhist population.

India claims that China occupies 38,000 sq km (15,000 sq mi) of territory on the Aksai-Chin Plateau which India considers to be part of Ladakh where the current confrontation is taking place.
