Many nations will decide there's no point moving ahead with trade pact in the absence of the United States

US President Barack Obama's landmark Trans-Pacific Partnership was already on life support before his successor, Donald Trump, promised American voters worried by the impact of globalization that he would kill it and bury it.

Now that the Republican-dominated Congress has announced it will not discuss ratification of the TPP during the remainder of Obama's term, all that is left for the outging president to do is read the funeral oration for the proposed Pacific Rim trade pact that had been the keystone of his administration's so-called "pivot to Asia".

That may come when Obama joins other regional leaders for an Asia-Pacific Economic Cooperation summit in Lima, Peru.

The demise of the TPP, which was to group 12 regional states in a wide-ranging, US-led trade alliance, offers an opportunity for China to assume leadership of an alternative free trade area.

President Xi Jinping, who was to be in Lima for the Nov 19-20 APEC Economic Leaders' Meeting, was widely expected to press for a Pacific partnership that, unlike TPP, would include both China and Russia.

Obama's sponsorship of the TPP had been viewed by Beijing as a potentially hostile attempt to write the trade rules for the benefit of the United States in the face of China's growing economic might.

As things have turned out, the US administration's failure to secure domestic support for the deal is likely to leave it marginalized in future regional trade agreements.

Trump's hostility to the TPP, which he described during his election campaign as a disaster "pushed by special interests who want to rape our country", won the backing of voters in traditionally industrial states who blame foreign competition, particularly from China, for job losses.

In an otherwise divisive campaign, it was a theme that united the candidates. Hillary Clinton went cool on a pact that she had previously supported, while her Democratic rival, Bernie Sanders, echoed Trump's view that it was disastrous.

The potential US partners in the TPP will almost certainly decide that there is no point moving ahead with the trade pact in the absence of what would have been its most powerful partner. Peru's President Pedro Pablo Kuczynski, the host, has said of the moribund pact: "It can be replaced with a similar deal, but without the United States."

Speaking to Russia Today, he said: "I think it would be best to have an Asia-Pacific deal that includes China, and includes Russia as well."

That alternative is likely to come in the context of negotiations on the Regional Comprehensive Economic Partnership. Talks on the RCEP, a mega grouping that could embrace almost half the world's population, were launched four years ago.

As the results of the US election came through, Australian Foreign Minister Julie Bishop reflected: "We see TPP as an important economic manifestation of the United States' presence in our region. Should it not go ahead, then the vacuum that would be created is most likely to be filled by RCEP."

Raul Salazar, a senior Peruvian trade official, told China's Xinhua in November: "China has contributed largely to pushing the idea of a free-trade area. Peru holds the position that we need an Asia-Pacific free-trade area."

What might be termed the "pivot to China" became apparent as a result of the uncertainties over trade prompted by the US political campaign. Rodrigo Duterte, president of the Philippines, for example, said during a visit to Beijing in October that he would reduce long-standing ties with the US in favor of better relations with China.

With the US on the retreat, and with a protectionist president heading for the White House, the way appears open for China to take the lead toward a proposed Free Trade Area of the Asia Pacific that Beijing has long championed as a rival and an alternative to the US-dominated TPP.
