The week begins two weeks after the US leader lost midterm elections. Some analysts see Trump's transactional style in Asia as a continuation of the pivot policy.
World leaders are flying to Asia this week for back-to-back high-level summits, placing the political centre of gravity firmly in the region.
The summit calendar also follows an awkward revelation about the head of Nvidia, the US chipmaker that for a long time was the world's most valuable company. US intelligence suspects that a woman with whom he was having an affair was a Chinese spy.
Issues expected to run through the meetings include artificial intelligence supply chains and governance, tariff reductions and the green energy transition.
Putin, meanwhile, wants to maintain his bargaining leverage over Ukraine, according to the account of the diplomatic week.
At the Asean summit, diplomats will also focus on Myanmar, which is seeking reintegration. Coup leader Min Aung Hlaing remains barred from Asean but is allowed to send a representative.
Despite monthly meetings, negotiations will have to continue next year, when Asean's leadership rotates to Singapore.
